RoHS Compliant Single Mode SFP Transceiver for GbE and Fiber
Channel
FEATURES
z Compliant with SFP Transceiver SFF-8472
MSA specification with internal calibration
z Compliant with Specifications for IEEE
802.3z/Gigabit Ethernet
z Single + 3.3V Power Supply and TTL Logic
Interface
z EEPROM with Serial ID Functionality
z Laser Class 1 Product which comply with the
requirements of IEC 60825-1 and IEC 60825-2
z Duplex LC Connector interface
Description
The LCP-1250 series are 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-1250 series are 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-1250 series
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
z Gigabit Ethernet
z Switch to Switch interface
z Switched backplane applications
z File server interface
Performance
z LCP-1250B4Mxx: 1310nm DFB laser, 21dB link
budget (40km)
z LCP-1250D4Mxx: 1550nm DFB laser, 17dB link
budget (40km)
z LCP-1250D4Wxx: 1550nm DFB laser, 21dB link
budget (70km)
z LCP-1250D4Rxx: 1550nm DFB laser, 25dB link
budget (80km)
z LCP-1250D4Vxx: 1550nm DFB laser, 30dB link
budget (100km)
