DESCRIPTION
The TRSL-7385W-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 27 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.
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.

Notes: 1. PIN 17 and 18 provide an analog voltage output proportional to the laser bias current, based on the following
formula: Ibias = V (Bmon+ - Bmon-) / 10 Ω. See below the equivalent circuit.
2. PIN 19 and 20 provide an analog voltage output proportional to the monitor photodiode current, based on the
following formula: Imon = V (Pmon+ - Pon-) / 200Ω. See below the equivalent circuit.
3. PIN 1 is used to monitor the received photocurrent. It must be connected to a positive voltage within the specified
above. The received power is given by the photocurrent multiplied by the photodiode responsivity.
