Fiber Channel. This module is designed for multi-mode
fiber and operates at a nominal wavelength of 850 nm. The
transmitter section uses a multiple quantum well VCSEL
and is a class 1 laser compliant according to International
Safety Standard IEC 60825. The receiver section uses an
integrated GaAs detector preamplifier (IDP) mounted in an
optical header and a limiting post-amplifier IC. A PECL
input / output logic interface is used. TTL RX-LOS output
simplifies interface to external circuitry. A 20-pin SCA-2
host connector is used to connect the converter to the host
system.
LASER SAFETY
This single mode transceiver is a Class 1 laser product. It

l Switch to Switch Interface
l High Speed Interface for File Servers
l Bus Extension Application
l Data Storage
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

A sequence value of 1 indicates that the signal is in the first group to engage during plugging of a module. A sequence value of 2
indicates that the signal is the second and last group. The two guide pins on the connector are electrically connected to the transceiver circuit
ground. These two guide pins make contact with circuit prior to sequence 1 signals.

protocol
Module Definition 4 specifies a serial definition protocol. For this definition, upon power up, MOD-DEF(1:2) appear as no connector
(NC) and MOD-DEF(0) is TTL LOW. When the host system detects this condition, it activates the serial protocol. The protocol uses the
2-wire serial CMOS E2PROM protocol of the ATMEL AT24C01A/02/04 family of components.
