Connectors

SC Connector SC stands for Subscriber Connector- a general purpose push/pull style connector developed by NTT. SC has an advantage in keyed duplexibility to support send/receive channels.

FC Connector FC stands for Fixed Connection. It is fixed by way of a threaded barrel housing. FC connectors are typical in test environments and for singlemode applications.

ST Connector

ST Adapter (mating sleeve)

ST Connector ST stands for Straight Tip- a quick release bayonet style connector developed by AT&T. STs were predominant in the late 80s and early 90s.

LC Connector (Simplex and Duplex

LC Simplex Adapter

LC Duplex Adapter

LC stands for Lucent Connector. The LC is a small form-factor fiber optic connector. The LC connector uses a 1.25 mm ferrule, half the size of the ST. Otherwise, it is a standard ceramic ferrule connector. The LC has good performance and is highly favored for singlemode.

MU Connector MU is a small form factor SC. It has the same push/pull style, but can fit 2 channels in the same footprint of a single SC. MU was developed by NTT.

ESCON Connector ESCON connectors derive their name from their original application, IBM's enterprise system connection (ESCON) for mainframe computers.

SMA Connector Amphenol developed the SMA from the "Subminiature A" hence SMA, microwave connector. The model 905 had a machined ferrule exactly 1/8 inch in diameter that mated in a machined adapter.

FDDI Connector

FDDI Connector FDDI connector utilizes two 2.5mm ferrules. The ferrules are sheltered from damage because of the fix shroud that has been constructed in the FDDI connector.

E2000 Connector and Adapter Externally a E2000 connector looks like a miniature SC connector. The connector is easy to install, with a pushpull latching mechanism which clicks when fully inserted.

MT-RJ Connector and Adapter MT-RJ connectors are used in intrabuilding communication systems. Since they are designed as plugs and jacks, like RJ-45 telephone connectors, adapters can be used with some designs, but are not required for all.

Strip fiber cable jacket. Strip fiber tubes Clean cable gel. Secure cable tubes. Strip first splicing fiber. Place the fusion splice protection sleeve. Clean the bare fiber Fiber cleaving Prepare second fiber being spliced. Fusion splicing Heat shrink the fusion splice protection sleeve. Place splice into splice tray. Perform OTDR test. Close the splice tray. Bidirectional OTDR test or power meter test. Mount the splice enclosure.

Fiber Optic Cable Mechanical Splices 



Fiber optic cable mechanical splicing is an alternate spicing technique which does not require a fusion splicer Mechanical splicing uses a small, mechanical splice, about 6cm long and 1cm in diameter that permanently joins the two optical fibers





A mechanical splice is a small fiber connector that precisely aligns two bare fibers and then secures them mechanically. Fiber optic cable mechanical splices are small, quite easy to use, and are very handy for either quick repairs or permanent installation
