1330 nm TX / 1270 nm RX , 10.3 Gbps 1-Fiber SM LC SFP+ Transceiver
**********************************************************************************************************************************************************************
FEATURES
DESCRIPTION
l 1-Fiber Bi-Directional SFP Optical Transceiver
l Up to 10.3 Gbps Bi-directional Data Links
l Compliant with SFP+ MSA
l Compliant to IEEE 802.3ae 10GBASE-BX
l Simplex LC Connector
The SPB-2920LG 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.
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.
l 1330 nm DFB LD Transmitter
l 1270 nm Receiver
l Distance Up to 20 km
l AC/AC Coupling according to MSA
l Single +3.3 V Power Supply
l RoHS Compliant
l 0 to 70oC Operating: SPB-2920LG
l -10 to 85oC Operating: SPB-2920BLG
l Class 1 Laser International Safety Standard IEC 60825
Compliant
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.

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 E2PROM protocol of the ATMEL AT24C01A/02/04 family of components.
