Single-mode fiber is the medium on the PA-A6-OC3SMI, the Cisco 1-port ATM OC-3c/STM-1 single-mode (IR) enhanced port adapter. The interface runs at 155.52 Mbps over 9-micron fiber on an SC connector, at 1260 to 1360 nm, for links up to 15 km.
Transmit power is -15 to -8 dBm, receive power is -28 to -8 dBm and the power budget is 15 dB. The PA-A6-OC3SML is the long-reach single-mode model at 45 km, the PA-A6-OC3MM is the multimode model at 2 km, and the PA-A6-T3 and PA-A6-E3 are the DS3 and E3 models.
Software starts at Cisco IOS 12.2(15)T or 12.3 Mainline on the Cisco 7200VXR and 7301, at 12.2(31)SB on the Cisco 7304, and at 12.3(1) on the Cisco 7500 with VIP4-50, VIP4-80 or VIP6-80. The FlexWAN module in the Cisco 7600 is supported from 12.2(14)SX. The port adapter is single width.
Two segmentation and reassembly processors, one for transmit and one for receive, handle AAL5 data traffic, and local buffer memory is partitioned per virtual circuit and per virtual path. Traffic shaping, ATM Forum UNI 3.0, 3.1 and 4.0 signaling and MPLS are supported. Other ATM and WAN port adapters are in the Cisco interface cards category.
