The MT4-M3-4D53L-I Multi-mode optical transceiver is 1 x 11 mini transceiver with LC 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. Operating temperature is from -40℃ to 85 ℃.
