1-Port OC-192 STM-64 POS RPR XFP SPA Overview
1-Port OC-192/STM-64 POS/RPR XFP SPA Interface Specifications
The framer processes 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-192/STM-64 frame.
The 1-Port OC-192/STM-64 POS/RPR XFP 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-192/STM-64 POS/RPR XFP SPA Optical Transceiver Modules,
Connectors, and Cables
The 1-Port OC-192/STM-64 POS/RPR XFP SPA uses a single-mode, 9.95 Gbps, OC-192 optical fiber
(SONET STS-192 or SDH STM-64) optical transceiver module for SONET and SDH connection to the
network.
The 1-Port OC-192/STM-64 POS/RPR XFP SPA supports the following types of optical transceiver
module:
•
Single-mode short-reach (SR) XFP module—XFP-10GLR-OC192SR
•
Single-mode intermediate-reach (IR) XFP module—XFP-10GER-OC192IR
•
Single-mode very-long reach XFP module—XFP-10GZR-OC192LR
Cisco Systems qualifies the optics that are approved for use with its SPAs. As of Cisco IOS XR Software
Release 3.4.0, the above-listed XFPs are the only optical transceiver modules qualified for use.
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) to connect your router to a network.
