1.25Gbps Single Fiber Bi-directional SFP Transceiver
(For 10km and 15km point-to-point transmission)
Members of FlexonTM Family
Description
Sourcephotonics 1.25G single fiber bi-directional
SFP transceivers are high performance, cost
effective modules, which supports data rate of
1.25Gbps and transmission distance up to 10km and
15km.
Features
ꢀ
1.25Gbps bi-directional data links
Up to 10km and 15km point-point transmission
SPS-34-GB-xx-xDFF is normally used in the client
side (ONU), which transmits 1310nm optical signal
and receives 1490nm optical signal. While
SPS-43-GB-xx-xDFF is used in the central office
side (OLT), which transmits 1490nm optical signal
and receives 1310nm optical signal.

Low EMI and excellent ESD protection
SFP MSA package with single SC receptacle
Single +3.3V Power Supply
The standard serial ID information compatible with
SFP MSA describes the transceiver’s capabilities,
standard interfaces, manufacturer and other
information. The host equipment can access this
information via the 2-wire serial CMOS EEPROM
protocol. For further information, please refer to SFP
MSA.
Detailed product information in EEPROM
Operating Case Temperature
Standard: -5 to +70°C
Industrial: -40 to +85°C
An enhanced Digital Diagnostic Monitoring Interface
compatible with SFF-8472 has been incorporated
into the transceivers. It allows real time access to
the transceiver operating parameters such as
transceiver temperature, laser bias current,
transmitted optical power, received optical power
and transceiver supply voltage by reading a built-in
memory with I2C interface.
