At 80 km, the SFP-OC3-LR2 is the longest-reach OC-3/STM-1 SFP in the Cisco range, running 155 Mbps over single-mode fiber. The 1480 to 1580 nm transmitter puts out 0 to -5 dBm, and the receiver covers -10 to -34 dBm with a 1 dB optical path penalty.
A second long-reach OC-3 model covers 40 km, the SFP-OC3-LR1, which has a 1263 to 1360 nm transmitter. Both use a dual LC/PC connector with PC or UPC patch cords, while APC patch cords are not supported.
The SFP-OC3-LR2 is a hot-swappable module for SFP-based POS, TDM and ATM interfaces on Cisco router products. Real-time readings of output power, input power, temperature, laser bias current and supply voltage come through the digital diagnostics. It is a Class 1 laser product with a 8.6 mm x 13.7 mm x 56.5 mm body. The SFP is compatible with the SONET/SDH and ATM standards. See the Cisco interface card category for other optics.
