1-Port Channelized Stm-16/Oc-48 Spa Cables And Connectors - Cisco XR 12000 Series Hardware Installation Manual

1-Port Channelized STM-16/OC-48 SPA Overview

1-Port Channelized STM-16/OC-48 SPA Cables and Connectors

The 1-Port Channelized STM-16/OC-48 SPA uses a small form-factor pluggable (SFP) optical
transceiver module installed in each port for SONET and SDH single-mode and multimode optical fiber
connection (see
Figure 2-23
The SFP optical transceiver modules used with the 1-Port Channelized STM-16/OC-48 SPA 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
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-16/OC-48 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.

SFP Optics Module
Multimode—2.488-Gbps, OC-48/STM-16 optical fiber (SONET STS-48 or SDH STM-16)
Use a multimode optical fiber that has a core/cladding diameter of 62.5/125 microns.
Single-mode—2.488-Gbps, OC-48/STM-16 optical fiber (SONET STS-48 or SDH STM-16)
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.)
