1-Port Channelized STM-1/OC-3 SPA Overview
1-Port Channelized STM-1/OC-3 SPA Interface Specifications
The framer processes incoming and outgoing SONET or SDH frames. The framer operates at
OC-3c/STM-1 line rates (155.52 Mbps).
Packet data is transported with a user-configured encapsulation (such as Point-to-Point Protocol [PPP]),
and is mapped into the STS-3c/STM-1 frame.
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
(See
Figure 3-8
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-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)
