8. 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) 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.
