FEATURES
DESCRIPTION
l 1-Fiber Bi-Directional SFP Optical Transceiver
l Compliant with IEEE 802.3ah-2004 1000BASE-BX
l Simplex SC Connector: SPB-7840WG
l Simplex LC Connector: SPB-7840LWG
l SFF-8472 Digital Diagnostic Function
l 1310 nm DFB LD Transmitter
l 1490 nm Receiver
The SPB-7840WG series is small form factor pluggable
module for Gigabit Ethernet 1000BASE-BX and Fibre
Channel single fiber communications by using 1310 nm
transmitter and 1490 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
l Distance Up to 40 km
l AC/AC Coupling according to MSA
l Single +3.3 V Power Supply
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 1490 nm
detector preamplifier (IDP) mounted in an optical header
and a limiting post-amplifier IC.
l RoHS Compliant
l 0 to 70oC Operating: SPB-7840WG
l -10 to 85oC Operating: SPB-7840BWG
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.

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