Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a terminal box and a photoelectric composite cable for a photoelectric composite cable,

The present invention relates to a terminal box and a photoelectric composite cable for a photoelectric composite cable. More particularly, the present invention relates to a terminal box and a photoelectric composite cable for a photoelectric composite cable having improved workability in connection work between a photoelectric composite cable and a jumper cable at a base station.

In the conventional mobile communication, a communication signal is transmitted from the base station to a base station, and an RF signal transmitted from a base transceiver station (BTS) of the base station is wirelessly transmitted through a base station antenna. Also, a radio signal transmitted from a user's portable terminal is received by the base station antenna, and the received signal is amplified through a TMA (Tower Mount Amplifier) and transmitted to the BTS.

At this time, although the BTS, the TMA and the antenna of the base station are connected by the coaxial feeder line, the signal loss is large as the length of the coaxial feeder cable increases. When the antenna is installed in a tower having a height of several tens of meters, a loss increases in a coaxial feeder line connecting a base station on the ground and the antenna, and a signal provided by the base station due to signal loss of the coaxial feeder is required To attenuate the signal without reaching the intensity of the signal, a Tower Mounted Amplifier (TMA) is installed to compensate and amplify the signal.

However, since the TMA consumes a relatively large amount of power in order to amplify the signal, the TMA requires a large amount of maintenance in terms of the overall system, which leads to a problem of inefficiency.

With the evolution of FTTx (Fiber to the X) and the miniaturization of repeaters, base station equipment has also evolved. The optical unit is characterized in that the signal attenuation according to the cable length is extremely small as compared with the coaxial cable. RRH (Remote Radio Head), which is a technology to convert optical signals into RF signals capable of emitting optical signals immediately before the antenna, has been introduced.

The remote radio head (RRH) is a complement to the inefficient disadvantages of power consumption and maintenance of a mobile communication base station using a conventional TMA. The RRH separates the RRU (Remote RF Unit) from the conventional BTS and places it remotely underneath the antenna of the base station tower.

The remaining parts of the existing BTS in which the RRU is separated in the RRH, that is, the BBU (Baseband Unit) and the PSU (Power Supply Unit) are connected to the RRU by a photoelectric hybrid cable including an optical unit and a power unit with little attenuation per length , A communication signal from a Baseband Unit (BBU) and a Power Supply Unit (PSU) is supplied to an RRU (Remote RF Unit) through an optical unit constituting the photoelectric hybrid cable, and the electric power is supplied to the RRU (Remote RF Unit).

Since the RRU (Remote RF Unit) can be installed just below the base station antenna at the top of the base station Tower, the length of the coaxial feeder for supplying the RF signal converted by the RRU (Remote RF Unit) to the antenna is minimized, Since the attenuation of the RF signal generated when the RF signal is transmitted through the line does not matter, the attenuation amount of the signal up to just before the radiation is minimized, and the necessity of the TMA using the conventional power consumption is eliminated. This technical feature has become a feature of the RRH in terms of the maintenance of the base station.

In this RRH system, the BBU (Baseband Unit), PSU (Power Supply Unit) and RRU (Remote RF Unit) are connected via a terminal box for photoelectric hybrid cable.

In other words, the photoelectric hybrid cable is composed of a plurality of RRUs (Remote RF Unit), which are installed in a BBU (Baseband Unit), PSU (Power Supply Unit) and one tower, A method in which a power unit and an optical unit are branched and connected to a plurality of RRUs in a terminal box for a photoelectric hybrid cable can be used.

When a single photoelectric composite cable is branched by a plurality of jumper cables, a plurality of power units and optical units constituting a photoelectric composite cable in a cable terminal box and a power unit and an optical unit constituting each jumper cable are housed in a terminal box To be connected using a connector or the like.

As the number of base station antennas increases depending on the communication company or the communication method, the number of RRUs or terminal boxes increases accordingly. Therefore, the number of RRUs may be large even when the number of photoelectric hybrid cables introduced into one terminal box is small. Therefore, the base station management worker needs to take a lot of time and effort because he / she must perform the connection work of disconnecting the photoelectric hybrid cable and connecting the power unit and the optical unit in the terminal box to the power unit of the jumper cable and the optical unit.

It is required to improve the connection work of the terminal box connecting the photoelectric composite cable and the jumper cable in a rapidly changing environment.

Like reference numerals designate like elements throughout the specification.

1 is a block diagram of a base station equipped with a terminal box 200 for a photoelectric hybrid cable according to the present invention.

The base station 1 of the RRH scheme is characterized in that the RRU 40 (Remote RF Unit) is separated from the base station of the conventional BTS system and is disposed under the antenna 20 of the base station tower and remotely controlled.

The remaining part 10 of the base station of the existing BTS system in which the RRU 40 is separated in the base station system 1 of the RRH scheme, that is, the baseband unit (BBU), the power supply unit (PSU) And is connected to a photoelectric hybrid cable 100 including a light unit and a power unit which are almost not used.

In the BBU (Baseband Unit) and PSU (Power Supply Unit), the communication signal is supplied to the RRU 40 through the optical unit constituting the photoelectric hybrid cable, and the power is supplied to the RRU 40 through the power unit constituting the photoelectric hybrid cable. .

Since the RRU 40 can be installed just below the base station antenna 20 at the top of the base station Tower, the length of the coaxial line 30 for supplying the RF signal converted from the RRU 40 to the antenna 20 The attenuation amount of the signal until just before the radiation is minimized and there is no need of the TMA which has used the conventional power consumption as much as the RF signal attenuation generated when the RF signal is transmitted through the coaxial line 30 is minimized. This technical feature has become a feature of the RRH in terms of the maintenance of the base station.

1, the BBU (Baseband Unit), the PSU (Power Supply Unit) and the RRU (Remote RF Unit) are connected to the terminal box 200 for the photoelectric hybrid cable according to the present invention. ).

In other words, the photoelectric hybrid cable 100 is a cabled optical unit and a power unit, and includes a portion 10 composed of a BBU (Baseband Unit) and a PSU (Power Supply Unit) A plurality of RRUs (Remote RF Unit) of the photoelectric hybrid cable can not be connected directly, and each optical unit and power unit constituting the photoelectric hybrid cable 100 are branched from the terminal box 200 for the photoelectric hybrid cable, And connected via a jumper cable 50, respectively.

 Recently, various kinds of portable terminals have been diversified, new and old terminals having different communication systems have been coexisted and communication towers have been installed. As a result of sharing an installation tower of the antenna 20 constituting the RRH between mobile communication providers, And RRUs, which make up dozens of RRHs, have been installed, making the tower a limited space for installation and increasing the burden on the installation.

Further, in the case where the operator works through the terminal box, the connection operation for connecting the optical unit and the power unit constituting the photoelectric hybrid cable 100 to the optical unit constituting the jumper cable 50 and the power unit requires a considerable working time Demand.

Therefore, the terminal box 200 for a photoelectric hybrid cable connected to various RRU equipment is also minimized in volume, so that it is possible to minimize the space restriction on the tower for installing the antenna 20, A terminal box is required.

Hereinafter, a structure of a photoelectric composite cable will be described, and then a terminal box for a photoelectric composite cable according to the present invention will be described in detail.

Figure 2 shows one embodiment of a photoelectric composite cable. More specifically, FIG. 2 (a) shows a perspective view of the photoelectric composite cable taken away at multiple stages, and FIG. 2 (b) shows a cross-sectional view of the photoelectric composite cable.

Referring to FIG. 2, the photoelectric hybrid cable 100 may include a cable core 105 and an outer layer 150 surrounding the cable core 105.

The cable core 105 may include a plurality of power units 110 for power supply, and a plurality of optical units 130 for transmitting optical signals.

A center line 145 may be provided at the center of the photoelectric hybrid cable 100 in order to prevent the photoelectric composite cable 100 from being bent more than necessary or to provide a supporting force against a tensile force.

The center line 145 is located at the center of the photoelectric hybrid cable 100 to provide resistance against repulsion or tensile force when the bending force acts on the photoelectric hybrid cable 100, 100) is prevented from breaking or breaking more than necessary, and serves to support the shrinkage of the tube due to the temperature change.

The cable core 105 may further include a filler 120 filling a gap between the plurality of power units 110 or the optical unit 130.

Since the power unit 110 has a circular shape, a gap or clearance is generated between neighboring power units. In such a configuration, the entire outer shape of the photoelectric composite cable 100 can not maintain its circular shape, and thus it is vulnerable to warping or impact acting on the outside.

A method of forming the metal protective layer 151 will now be described with reference to a method of supplying a plate type metal plate together with a cable core 105 including an optical unit 130 and a power unit 110, And the end portions of the metal plate are joined to each other by welding or the like to form a pipe having a predetermined diameter. And then pressed at predetermined intervals so as to form a wrinkle on the outside of the pipe.

The outer cover layer 150 provided at the outermost portion of the photoelectric hybrid cable 100 forms the outer shape of the photoelectric composite cable 100 and includes an optical unit 130 and a power unit 110 ).

The outer cover layer 150 is in contact with the cable core 105 and surrounds the cable core 105 in a circular shape and has a metal protective layer 151 for protecting the cable core 105 from external impact, And an outer jacket 155 surrounding the outer jacket 151.

The outer jacket 155 may be made of a resin having a flame retardant property and being environmentally friendly. For example, the outer jacket 155 may be made of polyethylene, polypropylene, or polyvinyl chloride (PVC).

The cable core 105 may further include a nonwoven fabric tape 153 surrounding the outer periphery of the cable core 105 and surrounding the power unit 110 and the optical unit 130 in a circular shape. The nonwoven fabric tape 153 may be disposed in a manner to enclose the optical unit and the power unit in the compressed nonwoven fabric.

The nonwoven fabric tape 153 may be formed in such a manner that the tape-shaped material is horizontally or vertically extruded.

The optical unit 130 may include any type of optical fiber including an optical fiber for transmitting an optical signal. For example, the optical unit 130 may include at least one optical fiber 133 and a tube 135 < / RTI > The tube 135 may comprise, for example, polybutylene terephthalate (PBT), polypropylene, polyethylene or polyvinyl chloride. In addition, the tube 135 may be filled with filler. For example, be filled with jelly or filled with a tensile material 137, such as an aramid yarn. The tensile material 137 is excellent in tensile force and is flexible, so that the cable can be stably installed.

Each power unit 110 includes a conductor 113 and an insulator 115 surrounding the conductor 113. The power unit 110 may have a shape conforming to a standard used for general power, and the plurality of conductors 113 may be twisted together. The conductor 113 may be formed of a metal such as copper or aluminum. The insulator 115 may be formed of a polymer resin such as polyethylene, polypropylene, or polyvinyl chloride.

The photoelectric hybrid cable 100 constitutes a jumper cable 50 connected to the remote wireless unit 40 after the power unit 110 and the optical unit 130 are branched in the terminal box 200 as described above It should be connected to the power line and the optical unit, respectively.

The power unit 110 and the optical unit 130 may be interfered with each other when the power unit 110 and the optical unit 130 are branched in the terminal box 200 and combined with the jumper cable 50 This is a major factor that increases the time and cost of constructing the terminal box 200 by lowering the work efficiency of the operator.
