1310nm 10km 10G SFP+ Optical Transceiver
Cisco SFP-10G-LR Compatible 10GBASE-LR SFP+ 1310nm 10km DOM LC SMF
Optical Transceiver
Product Descriptions
Cisco SFP-10G-LR designed for use in 10-Gigabit Ethernet links up
to 10km over SingleMode fiber. Low power consumption and low latency allow your network devices to
work efficiently, and the DDM function supports real-time
monitoring for transceiver status.

Note:
1. Connected directly to TX data input pins. AC coupling from pins
into laser driver IC.
2. Into 100Ω differential termination.
3. 20 – 80%. Measured with Module Compliance Test Board and OMA
test pattern. Use of four 1’s and four 0’s sequence in the PRBS 9
is an acceptable alternative.
4. LOS is an open collector output. Should be pulled up with 4.7kΩ
– 10kΩ on the host board. Normal operation is logic 0; loss of
signal is logic 1.
