SPA-2XOC48POS/RPR Cisco 2-Port OC-48c/STM-16c POS/RPR Shared Port Adapter

The SPA-2XOC48POS/RPR is a Cisco 2-port OC-48c/STM-16c POS/RPR shared port adapter with SFP optics. It works as a packet over SONET/SDH interface and also complies with the IEEE 802.17 Resilient Packet Ring standard and supports the Spatial Reuse Protocol (IETF 2892). The OC48 SPAs run in tri-mode as POS, DPT or 802.17 RPR interfaces, and POS mode works on every platform that supports the adapter while DPT and RPR need additional software support.

Each port takes an SFP module, and Cisco offers three reaches: the SFP-OC48-SR single-mode short-reach module for up to 2 km, the SFP-OC48-IR1 intermediate-reach module for up to 15 km and the SFP-OC48-LR2 long-reach module for up to 80 km. The adapter has status LEDs for the SPA and for each port, with Carrier/Alarm, Active/Loopback, Protect and Pass Through indicators.
