The module is suitable for tests and measurements of high dense wavelength division multiplexing devices, waveguide grating arrays, planar lightwave circuits, Erbium-doped optical fiber amplifiers and other fiber optic components. It can also be applied in fiber grating and other. An SFP (Small Form-factor Pluggable) is a compact, hot-pluggable transceiver module that allows networking equipment — including switches, routers, servers, and media converters — to support different physical media, such as optical fiber or copper, without replacing the host hardware. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside. UC INSTRUMENTS' GM82009 is a high power fast and continued tuning tunable laser source module. The output can be tuned to any wavelength within C band or L band or C+L band. The GM82009 module is compact in.
