FC-PI 100-M5-SN-I Rev.13 

 

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-1250A4FDRx 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-1250A4FDRx series are designed to 

be compliant with SFF-8472 SFP Multi-source 
Agreement (MSA) with digital diagnostic 
monitoring functions: Temperature, V

CC

, TX 

optical power, TX laser bias current, and RX 
received optical power. 

The post-amplifier of the LCP-1250A4FDRx 

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 

 

Gigabit Ethernet 

 

Switch to Switch interface 

 

Switched backplane applications 

 

File server interface 

Performance 

 

850nm VCSEL Link up to 550m in 50/125

µ

Multi Mode Fiber
