PMI-10G-K
Photodiode module with TIA with AGC, 10 Gbps
DESCRIPTION
In this module a PIN InGaAs photodiode (working wavelength range 1260 – 1620 nm) is integrated with a low noise high gain TIA with auto gain control (AGC). It is equipped with an SM or MM fiber.
PMI-10G-K-RM is the module with optical matching (space between a fiber and a photodiode is filled with an index-matched medium).
PMI-10G-K-R50 provides low back reflection (<-50 dB). Applications: optical communications.
