The SFP-OC12-LR2 is the longest-reach OC-12/STM-4 SFP in the Cisco range, at 80 km over single-mode fiber and 622 Mbps. It plugs into SFP-based POS, TDM and ATM interfaces on Cisco router products and is compatible with the SONET/SDH and ATM standards.
Transmitter wavelength is 1480 to 1580 nm and transmit power runs from +2 to -3 dBm, while the 40 km long-reach OC-12 model works at 1280 to 1335 nm. The receiver range is -8 to -28 dBm and the optical path penalty is 1 dB. Connectors are dual LC/PC, and APC patch cords are not supported.
Digital optical monitoring reports output power, input power, temperature, laser bias current and supply voltage. The SFP is 8.6 mm high, 13.7 mm wide and 56.5 mm long, hot-swappable, and a Class 1 laser product. At 40 km, the OC-3 SFP-OC3-LR1 is a shorter-reach option in the same Cisco family of optics. Further modules are in the Cisco interface card category.
