Description

Device and method for laying pigtails

Technical field

The present invention relates to the field of communications, and in particular, to an apparatus and method for deploying pigtails into an open bellows.

Background of the invention

In communication networks, devices and ODF (optical distribution) Frames, fiber distribution frames are connected by pigtails. Usually, pigtails need to be installed when installing equipment. Especially on some transmission network equipment, there are many pigtails that need to be connected to the ODF. The pigtail is a relatively fragile connecting cable. In many site machines, the open fiber bellows is required to protect the pigtail from external factors.

At present, during the installation of the site equipment, the operation of laying the pigtail into the open bellows requires the installer to complete it by hand. In this way, at least the following disadvantages exist. Because the bellows has a small opening and the material is hard, a single installer cannot open the bellows with one hand to plug the pigtail. Therefore, two or two are required for laying the pigtail into the open bellows. With the above installation personnel, one person can open the bellows and the other can insert the pigtail into the corrugated pipe to complete the installation smoothly, which will result in waste of human resources and long working hours. In addition, the bellows is open. The location is sharper and often results in unprotected installers getting injured or damaging the fiber.
