Fiber Optic Patch Cord Wiki

optical 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 the terminal box. This is known as “interconnect-style cabling”.

Construction

optical fiber jumper is constructed from a core with a high refractive index, surrounded by a coating with a low refractive index that is surrounded by a protective jacket. Transparency of the core permits transmission of optic signals with little loss over great distances. The coating’s low refractive index reflects light back into the core, minimizing signal loss. The protective jacket minimizes physical damage to the core and coating.

Size

Ordinary cables measure 125µm in diameter (a strand of human hair is about 100µm). The inner diameter measures 9µm for single-mode cables, and 50/62.69µm for multi-mode cables.

The development of “reduced bend radius” fiber in the mid-2000s, enabled a trend towards smaller cables. Each unit of diameter reduction in a round cable, produces a disproportionate corresponding reduction in the space the cable occupies.

Classification

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 °).

Applications

Patch cables are used for connections to CATV (Cable Television), telecommunication networks, computer fiber networks and fiber test equipment. Applications include communication rooms, FTTH (Fiber to The Home), LAN (Local Area Network), FOS (fiber optic sensor), Fiber Optic Communication System, Optical fiber connected and transmitted equipment, Defense combat readiness, etc.

FiberStore supply fiber optic patch cable with different connector and cable type. The common core sizes of multimode fiber are OM1 62.5 micron and 50 micron in OM2 or 10 Gigabit Laser Optimized OM3. We offersingle mode fiber patch cables and multimode fiber patch cable with a variety of connector types such as LC, FC, SC, ST, MU, MTRJ and E2000.Duplex fiber cables consist of two fiber cores and can be either multimode or singlemode. We also can customize patch cables in any cut length.
