1. Basic Introduction:
Optical Fiber Patch Cord market, also known as fiber optic patch cable, fiber jumper, or fiber patch leads, it is an Optical Fiber Patch Cord is a fiber optic cable capped at either end with connectors that allow it to be rapidly and conveniently connected to CATV, an optical switch or other telecommunication equipment. Its thick layer of protection is used to connect the optical transmitter, receiver, and terminal box. This is known as "interconnect-style cabling".Rapid adoption of optical fibers across various industries such as data centers is the major factor that drives the growth of the optical fiber patch cord market.
We offer a range of standard patchcords and pigtails. These utilize common fiber optic patch cord connectors and optical fibre including 9/125 OS1 (OS2) Singlemode, 50/125 OM2,3 and 4 Multimode, and 62.5/125 OM1 Multimode and are available in 1,2,3,5 and 10m configurations to suit most installation needs.

7. How to choose Fiber patch cords?
1)Fiber Cable Mode: Single Mode or Multimode
The mode of fiber patch cables indicates how light beams travel within the fiber. There are two fiber cable modes: single mode and multimode.
2)Number of Fiber Strands: Simplex or Duplex
According to the number of fiber strands, there are simplex and duplex fiber patch cord. As shown in Figure 2, simplex fiber patch cord contains one single strand of fiber with one simplex connector on each end. It can be linked with a pair of BiDi transceiver modules featuring with one port. Whereas duplex fiber patch cord consists of two strands of glass or plastic with one duplex connector (or considered as two simplex connectors). It is often linked with common transceivers or dual fiber BiDi transceivers.
3) Choose the Right Cable Jacket Type (PVC/LSZH/OFNP/Armored)
Usually, there are three cable jacket types: Polyvinyl Chloride (PVC), Low Smoke Zero Halogen (LSZH) and Optical Fiber Nonconductive Plenum (OFNP). You can see there features in figure below and choose the right one for your network.
4) Connector Type: LC, SC, ST or Others
There are many connector types used in fiber patch cables such as LC, SC, ST, MTP or MPO listed in this article How Many Fiber Connector Types Do You Know? Aside from these connectors, there is a latest connector design called MDC connector, which enables the highest achievable connector density by delivering a 3X advantage over a standard LC connector. The different connector types are to plug into different interfaces, so you’d better affirm the interface type of the devices you are using the first time.
5) Choose the Right Connector Polish Type (UPC/APC)
Since the loss of the APC connector is lower than UPC connectors, usually, the optical performance of APC connectors is better than UPC connectors. In the current market, the APC connectors are widely used in applications such as FTTx, passive optical network (PON) and wavelength-division multiplexing (WDM) that are more sensitive to return loss. But APC connector is usually expensive than UPC connector, so you should weigh the pros and cons. With those applications that call for high precision optical fiber signaling, APC should be the first consideration, but less sensitive digital systems will perform equally well using UPC. Usually, connector color of APC patch cable is green, and of UPC patch cable is blue.
