DESCRIPTION

The TRSL-7385C-CXX0G series single mode transceivers
is low power, high performance CWDM modules for
bi-directional serial optical data communications such as
IEEE 802.3z Gigabit Ethernet 1000BASE and Fiber
Channel 1X SM-LC-L FC-PI. There are eighteen center
wavelengths available from 1270 nm to 1610 nm, each step
20 nm. A guaranteed minimum optical link budget of 27 dB
is offered. The transmitter section uses a multiple
quantum well 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.

LASER SAFETY

This single mode transceiver is a Class 1 laser product. It
complies with IEC-60825 and FDA 21 CFR 1040.10 and

1040.11. The transceiver must be operated within the
specified temperature and voltage limits. The optical ports
of the module shall be terminated with an optical connector
or with a dust plug.
