C Operation
Class 1 Laser International Safety Standard IEC 60825
Compliant
The SPB-9740G series is high performance module for
OC-48 / STM-16 and Gigabit Ethernet 1000BASE 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 DFB laser and is a class 1
laser compliant according to International Safety Standard
IEC 60825. The receiver section is designed to receive 1310
nm signal. 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 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.

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 E
2
PROM protocol of the ATMEL AT24C01A/02/04 family of components.
