Cisco ASR 9000 Series - 1-Port Channelized STM-1;OC-3 SPA Cables and Connectors

The 1-Port Channelized STM-1/OC-3 SPA supports Frame Relay Fragmentation (FRF.12) and Multilink
Frame Relay (MFR) features for Cisco IOS XR Software Release 4.0.1 and later releases.
Note
1-Port Channelized STM-1/OC-3 SPA Cables and Connectors
The 1-Port Channelized STM-1/OC-3 SPA uses a small form-factor pluggable (SFP) optical transceiver
module installed in the port for SONET and SDH single-mode and multimode optical fiber connection (see
the below figure).
Figure 26: SFP Optics Module
The SFP optical transceiver modules used with the 1-Port Channelized STM-1/OC-3 SPA provide the following
optical fiber options:
• Multimode—155-Mbps, OC-3/STM-1 optical fiber (SONET STS-3 or SDH STM-1)
Use a multimode optical fiber that has a core/cladding diameter of 62.5/125 microns.
• Single-mode—155-Mbps, OC-3/STM-1 optical fiber (SONET STS-3 or SDH STM-1)
Use a single-mode optical fiber that has a modal-field diameter of 8.7 ±0.5 microns. (Nominal diameter is
approximately 10/125 microns.)
For single-mode and multimode optical fiber connections, you can use either a duplex LC-type cable (see the
below figure) or two simplex LC-type cables, one for transmit (TX) and one for receive (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 1-Port Channelized STM-1/OC-3 SPA-equipped routers back to
back.
Long-range SFP optical transceiver modules (for long-reach configurations) cannot be connected back-to-back
without using an attenuator between the two of them.
