HBA card

April 13, 2012

Short for host bus adapter. An HBA is an I/O adapter that sits between the host computer's bus and the Fibre Channel loop and manages the transfer of information between the two channels. In order to minimize the impact on host processor performance, the host bus adapter performs many low-level interface functions automatically or with minimal processor involvement.

Fiber optical patch cord

April 13, 2012

A patch cable or patch cord is an electrical or optical cable used to connect ("patch-in") one electronic or optical device to another for signal routing. Devices of different types (e.g., a switch connected to a computer, or a switch to a router) are connected with patch cords. Patch cords are usually produced in many different colors so as to be easily distinguishable, and are relatively short, perhaps no longer than two meters. Types of patch cords include microphone cables, headphone extension cables, XLR connector, Tiny Telephone (TT) connector,RCA connector and ¼" TRS connector cables (as well as modular Ethernet cables), and thicker, hose-like cords (snake cable) used to carry video or amplified signals. However, patch cords typically refer only to short cords used with patch panels.

OM3 patch cord

April 13, 2012

OM3 patch cord is one kind of patch cords. OM3 is a standard which is the next generation of 50-micron multimode fiber. In essence, OM3 is a new laser-optimized fiber. Its refractive index profile is optimized for the 850nm wavelength when the laser inserting. It can be used to support traditional network, but most of time are used in 10G base-SR/SW. So OM3 patch cord is a patch cord which under the standard of OM3 applied in 10G base-SR/SW.
