Class 1 Laser International Safety Standard IEC 60825
Compliant
The SPB-8620LWG series is small form factor pluggable
module for 4x/2x/1x Fibre Channel and 1000BASE-BX
Gigabit Ethernet single fiber communications by using 1310
nm transmitter and 1550 nm receiver. It is with the SFP
20-pin connector to allow hot plug capability. Digital
diagnostic functions are available via an I
2
C series bus
specified in the SFP MSA SFF-8472. The transmitter
section uses a multiple quantum well 1310 nm DFB laser
and is a class 1 laser compliant according to International
Safety Standard IEC 60825. The receiver section uses an
integrated 1550 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.
