Description
The LCP-1250B4QDRx 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-1250B4QDRx 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-1250B4QDRx
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-1250B4QDRx: 1310nm FP laser, 10.5dB
link budget (10km)
