:: Choice of connectors

Ferula
The ring is the central part of the connector. Contains fiber optics in a central hole. Shell can be made of ceramic zirconium (), stainless steel or composite material.
Ceramic bushing is the most popular material because it has stable temperature characteristics. The most common is the zirconium ceramic is a hard, white ceramic. Ceramic bushing is used for both singlemode and multimode connectors. It offers the lowest loss insertion and better repeatability.
Connector Body
Fiber optic connector body may be steel or plastic. The design of the different body connector to connector. The connector body provides the mechanism for holding parties and the tip of the others put together. It establishes the mechanism locking connector. The most common mechanisms include the blocking of push-pull, snap, and turn thread of existence.
Connector Cap

Relief starting voltage
Strain relief boot is the part that connects the body of connector and fiber optic cable. It is often made of rubber. Although it seems small, is actually one of the most critical in a connector. Relieves stress on the fiber to prevent micro-bending, last minute and provides mechanical support Fiber optics and manipulation of the connectors.
:: Legacy Fiber Connector Types
The following list shows the types of legacy connectors have been deployed in many optical fiber networks for many years.
ST connector
ST connector was once the most popular connector for fiber. It appreciates both the individual mode and multimode fiber connections. The insertion loss using an ST connector is about 0.5 dB.
ST connector has a turn on the locking mechanism is not likely that the release into the environment vibrant. It is most often used in local networks.

D4 Connector
The NEC is probably the tip of D4 connector first to use steel or stainless steel, ceramic-ceramic /. He uses a nozzle smaller than CBS or FCS. It is widely used in telecommunications networks in the 80's to early 90 and some may still be in use.
FDDI Connector
Besides the SC Duplex, occasionally can see both sides FDDI connectors that mate to their specific networks. They are usually is used to connect the equipment into an outlet, but the rest of the network will have ST or SC connectors. , Both of which use 2.5 mm terminals, can be mated with connectors SC or ST adapters.
Biconical connector
Corpus luteum shows a connector versions Biconique SM version – mutlimode were usually black. Connector biconical was developed by a team led by Jack Cook, Bell Laboratories in Murray Hill, NJ.
