The SFP-OC3-LR1 is a Cisco OC-3/STM-1 long-reach SFP optics module for POS, TDM and ATM interfaces on Cisco routers. It runs at 155 Mbps over single-mode fiber with a typical distance of 40 km, uses a dual LC/PC connector and is a hot-swappable optical interface.
The transmitter wavelength range is 1263 to 1360 nm with a transmit power range of 0 to -5 dBm. The receiver power range is -10 to -34 dBm and the optical path penalty is 1 dB. Digital optical monitoring provides real-time access to optical output power, optical input power, temperature, laser bias current and supply voltage.
The module measures 8.6 x 13.7 x 56.5 mm (H x W x D). The case temperature range for operation and storage is -5 to 85 C (23 to 185 F). It is a Class 1 laser product, and the optics follow GR-253, ITU G.957 and G.707. Only patch cords with PC or UPC connectors are supported; APC connectors are not supported.
A related OC-3 interface is the PA-POS-OC3SMI OC-3c/STM-1 single-mode port adapter, and a single-mode gigabit SFP is the GLC-LH-SMD 1000BASE-LX/LH SFP. More optics are in Cisco interface cards.
