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 1662, PPP in HDLC-like Framing
• RFC 2615, PPP over SONET/SDH
For information on SNMP MIB support, see “Implementing SNMP on Cisco IOS XR Software” in

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. Only Very Short Reach
(VSR) optics are supported.
The 1-Port OC-192c/STM-64 POS/RPR VSR Optics SPA uses multimode MTP-type connectors:
• Multimode—9.95 Gbps, OC-192 optical fiber (SONET STS-192c or SDH STM-64c)
Use a multimode optical fiber that has a modal-field diameter of 8.7 ±0.5 microns. (Nominal
diameter is approximately 10/125 microns.)
MATESYNC Off Off Mate port is not synchronized.
Green On Mate port is synchronized.
CARRIER Off Off Port is not enabled by software.
Green On Port is enabled by software, and there is a valid SONET signal
without alarms.
Amber On Port is enabled by software, and there is at least one alarm
(LOS, LOF, RDI, and so on).
Blinking SRP mode mismatch alarm is indicated.
ACTIVE Off Off Port is not enabled by software.
Green On Port is enabled by software, and loopback is off.
Amber On Port is enabled by software, and loopback is on.
STATUS Off Off SPA power off.
Green On SPA is ready and operational.
Amber On SPA power is on and good, and the SPA is being configured.
