The SPB-2940LWG series single mode transceiver is small
form factor pluggable module for bi-directional serial optical
data communications such as IEEE 802.3ae 10GBASE-BX
by using 1330 nm transmitter and 1270 nm receiver. It is
with the SFP 20-pin connector to allow hot plug capability.
Digital diagnostic functions are available via an I2C series
bus specified in the SFP MSA SFF-8472. The transmitter
section uses a multiple quantum well 1330 nm DFB laser
and is a class 1 laser compliant according to International
Safety Standard IEC 60825. The receiver section uses an
integrated 1270 nm detector preamplifier (IDP) mounted in
an optical header and a limiting post-amplifier IC.

Interpretation by Host
Serial module definition
protocol
Module Definition 4 specifies a serial definition protocol. For this definition, upon power up, SDA and SDL appear as no connector
(NC) and MOD-ABS 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.
