Class 1 Laser International Safety Standard IEC 60825
Compliant
The SPB-7720G series is small form factor pluggable
module for Gigabit Ethernet 1000BASE-BX and Fibre
Channel 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 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.

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.
