A 2 dB optical path penalty is specified for the SFP-OC48-LR2, where the other Cisco SONET/SDH SFPs in this data sheet list 1 dB. It is the OC-48/STM-16 long-reach model, reaching 80 km over single-mode fiber for SFP-based POS, TDM and ATM interfaces on Cisco router products.
The transmitter runs at 1500 to 1580 nm with +3 to -2 dBm of output power, and the receiver range is -9 to -28 dBm. The dual LC/PC connector is supported with PC or UPC patch cords only. The optical specification follows GR-253, ITU G.957 and G.707, and the SFP is compatible with the SONET/SDH and ATM standards.
Digital diagnostics cover output power, input power, temperature, laser bias current and supply voltage. The SFP is hot-swappable and a Class 1 laser product, 56.5 mm long, 13.7 mm wide and 8.6 mm high. Its 2 km OC-48 counterpart is the short-reach model, and other Cisco SFP optics are under Cisco interface cards.
