RoHS Compliant Single Mode SFP Transceiver for GbE and Fiber
Channel
FEATURES
Compliant with SFP Transceiver SFF-8472
MSA specification with internal calibration
Compliant with Specifications for IEEE
802.3z/Gigabit Ethernet
Single + 3.3V Power Supply and TTL Logic
Interface
EEPROM with Serial ID Functionality
Laser Class 1 Product which comply with the
requirements of IEC 60825-1 and IEC 60825-2
Duplex LC Connector interface
Description
The LCP-1250B4MDRx is hot pluggable 3.3V
Small-Form-Factor transceiver modules designed
expressly for high-speed communication
applications that require rates up to 1.25Gb/s.
The transceiver is data rate transparent, which
means it can support GbE (1.25Gb/s) as well as
1x Fiber channel (1.062Gb/s) operations.
The LCP-1250B4MDRx is designed to be
compliant with SFP Multi-source Agreement
(MSA). Digital diagnostic monitoring functions
(Temperature, V
CC
, TX optical power, TX laser
bias current, and RX received optical power)
compliant with SFF-8472 are also available. See
order information for details.
The post-amplifier of the LCP-1250B4MDRx
also includes a Loss of Signal (LOS) circuit that
provides a TTL logic-high output when the
received optical level is below a preset LOS
Assert threshold.
Applications
Gigabit Ethernet
Switch to Switch interface
Switched backplane applications
File server interface
Performance
LCP-1250B4MDRx: 1310nm DFB laser, 19dB
link budget (40km)
