FC/PC connector. The FC connector is a fiber-optic connector with a threaded body, which was designed for use in high-vibration environments. It is commonly used with both single-mode optical fiber and polarization-maintaining optical fiber. FC connectors are used in datacom, telecommunications, measurement equipment, and single-mode lasers.
The parts are typically identified by adding "/APC" (angled physical contact) to the name. For example, an angled FC connector may be designated FC/APC, or merely FCA. Non-angled versions may be denoted FC/PC or with specialized designations such as FC/UPC or FCU to denote an "ultra" quality polish on the fiber end face.
An APC connector's inserted core cover is oblique (about 30°, ±5°). [3] To reduce the back reflection of a connector, UPC polish is used. Industry standard is a maximum of −40 dB for PC back reflection measurement and −50 dB for UPC back reflection measurement. If even less back reflection is required, an APC might be necessary.
A fiber optic coupler is a device used in optical fiber systems with one or more input fibers and one or several output fibers. Light entering an input fiber can appear at one or more outputs and its power distribution potentially depending on the wavelength and polarization.

There are inexpensive adapters allowing SFP transceivers to be placed in a QSFP port. Both a SFP-DD, [10] which allows for 100 Gbit/s over two lanes, as well as a QSFP-DD [11] specifications, which allows for 400 Gbit/s over eight lanes, have been published. [12] These use a form factor which is directly backward compatible to their respective ...
Dual port 8 Gb FC host bus adapter card Dual port 16 Gb FC host bus adapter card. Fibre Channel HBAs, as well as CNAs, are available for all major open systems, computer architectures, and buses, including PCI and SBus. HBAs connect servers to the Fibre Channel network and are part of a class of devices known as translation devices.
The basic connector unit is a connector assembly. A connector assembly consists of an adapter and two connector plugs. Due to the sophisticated polishing and tuning procedures that may be incorporated into optical connector manufacturing, connectors are generally assembled onto optical fiber in a supplier's manufacturing facility.
