Fiber optic jumper cables are available in OS1, OS2 single-mode and OM1, OM2, OM3, OM4
multimode types. Both ends of the optical cable are terminated with a high performance hybrid or
single type fiber optic connector, such as SC connector, ST connector, FC connector, LC connector,
MTRJ connector, or E2000 connector in simplex or duplex. There are so many kinds of fiber optic
patch cables for various applications. How to choose right fiber optic patch cables for your networks?
This post provides a selection guide for you.
Step 1: Choose the Right Connector Type
A fiber optic patch cable is terminated on both ends with a fiber optic connector, such as LC
connector, SC connector, ST connector, FC connector, or MPO/MTP connector. Different connectors
are used to plug into different devices. If ports of devices in the both ends are the same, we can use
fiber optic patch cables with the same type of connectors on both ends, such as LC LC cables, SC SC
fiber patch cord, ST ST fiber patch cable, or MPO-MPO patch cables. If you want to connect different
ports type devices, fiber optic patch cables with different types of connectors on both ends, like LC
SC fiber patch cable, LC to ST fiber patch cable, or SC to ST fiber cable, may suit you.
Step 2: Choose the Right Connector Polish Type
Other than choosing the right connector type, you also need to choose the right connector polish
type, whether the same polish type of the same connector type or different polish types of different
connector types on both ends, such as SC APC fiber patch cord, SC/APC to LC patch cable. The loss
of APC connectors is lower than UPC connectors. Usually, the optical performance of APC
connectors is better than UPC connectors. 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 more expensive than UPC connector. 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.
Step 3: Choose Single-mode or Multimode Cable Type?
Fiber optic patch cable has two propagation modes: multi-mode and single-mode. Single-mode
fiber patch cord uses 9/125um glass fiber. It is designed for the transmission of a single ray or mode
of light as a carrier and is used for long-distance signal transmission. Multimode fiber patch cord
usually uses 50/125um or 62.5/125um glass fiber. It can carry multiple light rays or modes, each at a
slightly different reflection angle within the optical fiber core. Multimode fiber optic patch cables is
used for relatively short distances because the modes tend to disperse over longer lengths. Typical
single-mode fiber optic patch cable used yellow fiber cable and multi mode fiber optic patch cable
used orange or aqua fiber cable.
Step 4: Choose Simplex or Duplex Cable Type?
Do you need simplex or duplex fiber optic patch cords? There is only one single strand of glass or
plastic fiber in a simplex fiber optic patch cord. It is often used where only a single transmit and/or
receive line is required between devices. A simplex fiber optic patch cord has only one fiber optic
connector at each end, often used for Bidirectional (BiDi) fiber optic transceivers. A duplex fiber
patch cord consists of two strands of glass or plastic fiber which are typically found in a
tight-buffered and jacketed "zipcord" construction format. The duplex fiber is most often used for
duplex communication between devices where a simultaneous and separate transmit and receive
are required. Duplex fiber patch cords are used for common transceivers. Simplex and duplex fiber

patch cords both are available in single mode and multi-mode.
Step 5: Choose the Right Cable Jacket
Usually, there are three types of cable jacket: 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.
Besides those three cable jacket types above, there is another common cable, armored cable. The
double tubing and steel sleeve construction make these patch cables completely light tight, even
when they are bent. These cables can withstand high crushing pressures, which makes them
suitable for running along floors and other areas where they may be stepped on. The tubing also
provides excellent cutting resistance, abrasion resistance, and high tensile strength.

Step 6: Choose the Right Cable Length
Fiber optic jumper cables are made in different lengths, usually from 0.5m to 50m. You can choose
an appropriate cable length according to the distance between the devices you want to connect.
Conclusion
When choosing a fiber optic patch cord, you need to take all these factors above into consideration.
Whether you need single-mode or multimode, simplex or duplex, APC or UPC connector polish type,
PVC or LSZH cable jacket, 5m or 15m cable length, you need to consider them all. By following these
steps and figuring out what you need exactly, you can make appropriate choices for your
applications.
