Patch Cables

A fiber optic patch cable is an optical communications cable with connectors at each end for rapid and convenient connection to your fiber optic network. Patch cables are also known as an interconnect cable, and to a lesser extent a patch cord or jumper.


Patch cords are classified by transmission medium (long or short distance), by connector construction and by construction of the connector's inserted core cover.

Transmission medium

Single-mode fiber is generally yellow, with a blue connector, and a longer transmission distance. Multi-mode fiber is generally orange or grey, with a cream or black connector, and a shorter transmission distance.

Connector construction

Connector design standards include FC, SC, ST, LC, MTRJ, MPO, MU, SMA, FDDI, E2000, DIN4, and D4. Cables are classified by the connectors on either end of the cable; some of the most common cable configurations include FC-FC, FC-SC, FC-LC, FC-ST, SC-SC, and SC-ST.

Inserted core cover

The connector's inserted core cover conforms to APC, UPC, or PC configuration. A UPC inserted core cover is flat and is used in SARFT and early CATV. An APC connector's inserted core cover is oblique (about 30 °, ±5 °). To reduce the back reflection of a connector,UPC polish. Industry standard is a minimum of–40dB for PC back reflec-tion measurement and–50dB for UPC back reflection measurement. If even less back reflection is required, an APC might be necessary. An APC connector has an 8ºangle cut into the ferrule. These connectors are identifiable by their green color. An APC polished connector has an Indus-try Standard Minimum of–60dB measurement. APC fiber ends have low back reflection even when disconnected.
