What is Fiber Optic Splicing?
Splicing is the practice of joining two fibers together without using connectors. Two types of fiber splices exist: fusion splicing and mechanical splicing. Splicing may be made during installation or repair. More ...
System Area Network Interface Cards
Whereas the standard network may use twisted-pair cabling, the System Area Network may use separate fiber-optic cabling. System Area Network interface cards are special high speed circuits that provide communications between the servers over the System Area Network. More ...
How to Choose the Proper Fiber Optic Connector for Your FTTH (Fiber To The Home) Installation
Fiber optic connectors can be divided into three groups: simplex, duplex and multiple fiber connectors. Simplex connector means only one fiber is terminated in the connector. Duplex connector means two fibers are terminated in the connector. More ...
