PDLC fiber optic patch cables are widely used in Huawei/ZTE projects, it is a popular FTTA cable. Our FTTA base station fiber jumper, very good to meet the needs of the market, for mobile base station speed up, universal coverage provides a large number of dedicated passive wire. In the mobile communication base station cabling, in the past RRU end (RF pull-out unit, commonly known as outdoor far end) and BBU (baseband processing unit, commonly known as indoor near end) used as the main connection cable, with fiber as the main carrier of communications began to become global, a large number of coaxial cables began to be replaced by fiber optic cables, The RRU-BBU connection cable of the mobile base station is also beginning to use fiber optic cable s (a) as the primary connection cable, i.e. to pull the fiber jumper for the FTTA base station.

  • Stable performance;
  • Fewer parts, simple assembly, convenient for users to use;
  • Flexible form, according to the user’s needs appropriate changes to the product’s opening size, tail attachment length, housing body material, etc. , interface form can be round can also be rectangular, tail attachment can be straight or curved, shell material has metal and non-metallic two, wherein non-metallic material because it is mold molding products, good consistency;
  • The resistance to salt fog is much better than that of metal housings. The insertion loss of the product is generally less than 0.5dB, and the anti-pull force can reach 100 to 300N according to different product structure.

PDLC fiber optic patch cables, different from ordinary indoor wiring fiber jumper, first of all, because of the RRU and BBU connection, most of the cable is long-term in the outdoor environment, which requires fiber optic jumper steam to be able to adapt to the performance of the conventional outdoor environment, such as waterproof, sun protection, anti-aging, strong anti-pull and so on.

And PDLC fiber optic cable in FTTA base station cabling environment, usually requires fiber optic cable has a good bending performance, in the case of ensuring strength, but also to ensure a certain degree of flexibility, easy to construct. About the selection of fiber optic cable, I use the base station to pull away from the special fiber optic cable, the use of external sheaths for sun protection and anti-aging, outdoor-grade LSZH material, durable, long service life.
Internal reinforcements, unified use of U.S. imports of DuPont Kevlar aramid, enhance anti-pull, aramid shares sufficient.

About the production of PDLC fiber optic patch cables, when the customer does not have to adapt the waterproof end of the case, I Division produced the ordinary pull far fiber jumper, two end joints, are using the branch sleeve tube process. The 2.8mm stainless steel spiral tube, not only to ensure flexibility, but also anti-pull, pressure-resistant, and stainless-steel material, long-term use will not exist rust. In order to further enhance the protection of the branch joint end, we can also according to customer requirements, in both ends of the addition of bellows, pull rings and other protective devices. Convenient for customers when using, pull, as well as in the field for fiber optic connectors to provide more protection! In terms of packaging, our packaging also has a very standardized standards, and strict packaging process. We can provide customers with all packaging customization services, including special winding coils, special label design, special bag design, special carton design, as well as special fiber optic cable printing services. Customers can according to their own requirements, arbitrarily customized their own product packaging style! Customer-ordered disk packaging customer-ordered bag packaging and for the RRU end, has a special waterproof connector matching selection of waterproof connector situation, I division can also help our customers to carry out accurate screening, selection.
