Class 1 Laser International Safety Standard IEC 60825
Compliant
The SPM-3702G series is small form factor pluggable
module for multi-mode fiber Fast Ethernet and OC-3 /
STM-1 SONET / SDH single fiber communications by using
1550 nm transmitter and 1310 nm receiver. It is with the SFP
20-pin connector to allow hot plug capability. The
transmitter section uses a multiple quantum well 1550 nm
laser and is a class 1 laser compliant according to
International Safety Standard IEC 60825. The receiver
section uses an integrated 1310 nm detector preamplifier
(IDP) mounted in an optical header and a limiting
post-amplifier IC.
LASER SAFETY
This multi-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.

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 E

PROM protocol of the ATMEL AT24C01A/02/04 family of components.
