Four SFP cages make up the SPA-4XOC3-POS, the Cisco 4-port OC-3c/STM-1c POS shared port adapter. The 2-port model in the same family is the SPA-2XOC3-POS. Each port carries HDLC (RFC 2615), PPP (RFC 1662) or Frame Relay (RFC 2427) with IPv4 and IPv6, using POS payload mapping with the 1 + x^43 self-synchronous scrambler.
Timing is local (internal) or loop (recovered from the network), and local and line loopback are available. The adapter supports online insertion and removal, field-replaceable SFP modules, 1 + 1 SONET APS and SDH linear MSP, and a single SPA software reset. Management uses the RFC 2558 SONET/SDH MIB and SNMP.
Optics are separate SFP modules. The SFP-OC3-MM and SFP-OC3-SR reach up to 2 km, the SFP-OC3-IR1 reaches 15 km, the SFP-OC3-LR1 40 km long-reach SFP reaches 40 km and the SFP-OC3-LR2 reaches 80 km.
Maximum power is 14 W without optics. The single-height card weighs 0.75 lb (0.34 kg) and measures 0.8 in. (2.03 cm) high, 6.75 in. (17.15 cm) wide and 7.28 in. (18.49 cm) deep. It fits the Cisco 7304, Catalyst 6500 Series, Cisco 7600 Series, ASR 1000 Series and, for the 4-port OC-3 POS SPA, the CRS-1 and CRS-3. Find more shared port adapters in Cisco interface cards.
