1-Port Channelized Stm-1/Oc-3 Spa Cables And Connectors - Cisco ASR 1000 Series Hardware Installation Manual

1-Port Channelized STM-1/OC-3 SPA Overview
The 1-Port Channelized STM-1/OC-3 SPAinterface is compliant with RFC 1619, PPP over
SONET/SDH, and RFC 1662, PPP in HDLC-like Framing. The 1-Port Channelized STM-1/OC-3 SPA
also provides support for SNMP v1 agent (RFC 1155–1157), and Management Information Base (MIB)
II (RFC 1213).

1-Port Channelized STM-1/OC-3 SPA Cables and Connectors

The 1-Port Channelized STM-1/OC-3 SPAuses a small form-factor pluggable (SFP) optical transceiver
module installed in the port for SONET and SDH single-mode and multimode optical fiber connection
(Figure
Figure 3-44
The SFP optical transceiver modules used with the 1-Port Channelized STM-1/OC-3 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-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.

SFP Optics Module
Multimode—155-Mbps, OC-3c/STM-1 optical fiber (SONET STS-3c or SDH STM-1)
Use a multimode optical fiber that has a core or cladding diameter of 62.5/125 microns.
Single-mode—155-Mbps, OC-3c/STM-1 optical fiber (SONET STS-3c 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.)
