A fiber-optic 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"General Characteristics
Fiber optic patch cords are characterized by:
Low insertion loss;
High return loss;
Good repeatability;
Good interchange;
Excellent environmental adaptability.
Construction
A fiber optic patch cord is constructed from a core with a high
refractive index, surrounded by a coating with a low refractive
index, that is strengthened by aramid yarns and 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 aramid yarns and outer jacket minimizes
physical damage to the core and coating.
Size
Ordinary cables measure 125 µm in diameter (a strand of human hair
is about 100 µm). The inner diameter measures 9 µm for single-mode
cables, and 50 / 62.5 µm 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.[1]
Classification
FC-APC/FC-PC patch cords
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.
