The OC-3c/STM-1 POS SPAs with small form-factor pluggable (SFP) optical transceiver modules provide SONET and SDH network connectivity with a per-port bandwidth of 155.52 Mbps. For more information about SPA bandwidth, see the "Bandwidth Oversubscription" topic in this chapter. For more information about SPAs and their compatibility with SIPs and modular optics, see the "Carrier Card and SPA Product Overview" chapter in this guide. The following sections describe the 2-Port and 4-Port OC-3c/STM-1 POS SPA: • OC-3c/STM-1 POS SPA LEDs, page 3-21 • OC-3c/STM-1 POS SPA Interface Specifications, page 3-22 • OC-3c/STM-1 POS SPA SFP Optical Transceiver Modules and Cables, page 3-22 OC-3c/STM-1 POS SPA LEDs The 2-Port and 4-Port OC-3c/STM-1 POS SPAs have three types of LEDs.
