Fifteen kilometers of single-mode fiber is the typical reach of the SFP-OC3-IR1, a Cisco OC-3/STM-1 intermediate-reach SFP running at 155 Mbps. It sits between the 2 km short-reach and the 40 km and 80 km long-reach SFPs in the Cisco OC-3 group.
Its transmitter covers 1261 to 1360 nm at -8 to -15 dBm, the receiver range is -8 to -28 dBm, and the optical path penalty is 1 dB. A dual LC/PC connector takes PC or UPC patch cords. The SFP plugs into SFP-based POS, TDM and ATM interfaces on Cisco router products.
Diagnostics are read through the digital monitoring interface: output power, input power, temperature, laser bias current and supply voltage. The module is hot-swappable, a Class 1 laser product and specified to GR-253, ITU G.957 and G.707. It is 56.5 mm long. Other Cisco SONET/SDH optics include the SFP-OC3-LR1, and the Cisco interface card category holds further modules.
