The SPB-8940LG series is small form factor pluggable module for 4x/2x/1x Fibre Channel and 1000BASE-BX Gigabit Ethernet single fiber communications by using 1490 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 1490 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
Module Definition 4 MOD-DEF2 PIN 4 SDA MOD-DEF1 PIN 5 SCL MOD-DEF0 PIN 6 LV-TTL Low Interpretation by Host Serial module definition 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 2PROM protocol of the ATMEL AT24C01A/02/04 family of components.
