The TRSL-7380W-CXX0 series single mode transceivers is small form factor, low power, high performance module for bi-directional serial optical data communications such as IEEE 802.3z Gigabit Ethernet 1000BASE-LX and Fiber Channel 1X SM-LC-L FC-PI. There are eighteen center wavelengths available from 1270 nm to 1610 nm. A guaranteed minimum optical link budget of 24 dB is offered. The transmitter section uses a multiple quantum well 1550 nm DFB laser and is a class 1 laser compliant according to International Safety Standard IEC-60825. The receiver section uses an integrated InGaAs detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC. A LVPECL logic interface simplifies interface to external circuitry.
