Termination
There are many different ways to terminate fibre cable. With glass fibre, multimode
cable termination is the easiest to learn. One simple procedure called “crimp and
cleave” is to crimp the connector on the fibre, this requires special pliers and then
cleave the fibre carefully. Another more reliable procedure is to use an epoxy to bond
the fibre into the connector; connectors are available with the adhesive already in the
connector. The connector is then heated with the help of a special oven for around 1
minute; the fibre is inserted in the connector and is then allowed to cool. These two
terminating methods both require equipment to prepare the fibre before mounting
the connector and to polish the fibre after the cable is terminated. In systems where
connection points are frequently changed the bonded fibre may be beneficial, as this
gives a more durable termination. There is a large number of different fibre connectors
available on the market, but primarily there are just four connectors that are used
industrially, these are:
SC simplex connector used for
multimode 2 km (1.24 mi)
or singlemode 15/40 km
(0.93/24.85 mi)
LC duplex connector used for
singlemode 15/40/85 km
(0.93/24.85/52.81 mi)
MTRJ duplex connector used for
multimode 2 km (1.24 mi)
or singlemode 15/40 km
(0.93/24.85 mi)
ST simplex connector used for
multimode 2 km (1.24 mi)
