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

, 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)
