1-Port Clear Channel OC-3, 3-Port Clear Channel OC-3, and 1-Port Clear Channel OC-12 ATM SPA Version 2 Overview

2-Port and 4-Port OC-3c/STM-1 ATM SPA Cables and Connectors

The 2-Port and 4-Port OC-3c/STM-1 ATM SPAs provide the following optical fiber options:
•
•
For single-mode and multimode optical fiber connections, you can use either a duplex LC-type cable (see
Figure
Figure 3-12
RX
Use single-mode (for intermediate- or long-reach configurations) or multimode optical fiber cable to
connect your router to a network or to connect two OC-3-equipped routers back-to-back.
Long-range SFP optics modules (for long-reach configurations) cannot be connected back-to-back
without using an attenuator between the two of them.

The SPA-1xOC3-ATM-V2, SPA-3xOC3-ATM-V2, and SPA-1xOC12-ATM-V2 is a single-height SPA
that installs into one SIP subslot. The Clear Channel OC-3 ATM SPA with SFP optical transceiver
modules provides SONET and SDH network connectivity with a per-port bandwidth of 155.52 Mbps.
The Clear Channel OC-12 ATM SPA with small form-factor pluggable (SFP) optical transceiver
modules provides SONET and SDH network connectivity with a per-port bandwidth of 622 Mbps. For
more information about SPA bandwidth, see the
