FT4-M3-4D23K-P020
1.25Gbp/s Ethernet, SFF Optical Transceiver
The FT4-M3-4D23K-P020 Multi-mode optical transceiver is 2 x 5 Small Form Factor（SFF）with LC-pigtail connector. This Multi-mode transceiver is low power, high performance module for such as Gigabit Ethernet and Fiber Channel communications. This module is designed for multi mode fiber and operates at a nominal wavelength of 850 nm. The transmitter section uses a Vertical-cavity surface-emitting laser (VCSEL) at 850 nm. This is a class 1 laser compliant according to International Safety Standard IEC-825. The receiver section uses an integrated GaAs detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC. A LVPECL logic interface simplifies interface to external circuitry.
