1-Port OC-192c/STM-64 POS/RPR VSR Optics SPA Overview
1-Port OC-192c/STM-64 POS/RPR VSR Optics SPA Interface Specifications
The 1-Port OC-192c/STM-64 POS/RPR VSR Optics SPA contains a SONET/SDH framer to process
incoming and outgoing SONET or SDH frames. The framer operates at OC-192/STM-64 line rates (9.95
Gbps). Packet data is transported with a user-configured encapsulation (such as Point-to-Point Protocol
[PPP]) and is mapped into the STS-192c/STM-64 frame.
The 1-Port OC-192c/STM-64 POS/RPR VSR Optics SPA interface is compliant with the following
RFCs:
•
RFC 1619,
PPP over SONET/SDH
•
RFC 1662,
PPP in HDLC-like Framing
•
RFC 2615,
PPP over SONET/SDH
.
The 1-Port OC-192c/STM-64 POS/RPR VSR Optics SPA also provides support for SNMP v1 agent
(RFC 1155–1157) and RFC 1213:
•
RFC 1155,
Structure and Identification of Management Information for TCP/IP-based Internets
•
RFC 1156,
Management Information Base for Network Management of TCP/IP-Based Internets
•
RFC 1157,
Simple Network Management Protocol (SNMP)
•
RFC 1213,
Management Information Base (MIB) for Network Management of TCP/IP-Based
Internets:MIB II
.
1-Port OC-192c/STM-64 POS/RPR VSR Optics SPA Fixed Optical Transceiver,
40-pin Connector, and Cables
The 1-Port OC-192c/STM-64 POS/RPR VSR Optics SPA uses fixed optical transceivers, one for receive
(RX) and one for transmit (TX), for SONET and SDH connection to the network. Very Short Reach
(VSR) optics only are supported.
The 1-Port OC-192c/STM-64 POS/RPR VSR Optics SPA uses single mode SC-type connectors:
•
Single-mode—9.95 Gbps, OC-192 optical fiber (SONET STS-192c or SDH STM-64c)
