Product Review

The Cisco SPA-4XOC3-POS-V2 module, compatible with a wide range of Cisco routers, offers four ports for increased connectivity options in networks requiring access, aggregation, or WAN uplinks. It supports essential network management protocols like SNMP and RFC 2558 MIB for SONET/SDH, alongside operational features such as Online Insertion and Removal (OIR) and comprehensive LED indicators for monitoring. However, its operational temperature range is limited to 5°C to 40°C, potentially restricting deployment in environments with more extreme conditions.


The Cisco SPA-4XOC3-POS-V2 is a high-capacity packet over SONET (POS) shared port adapter designed to support a wide range of applications including access and aggregation, WAN uplinks, and internet peering. This device is compatible with multiple Cisco router series including the 12000, XR 12000, ASR 1000, and ASR 9000. It offers four ports, providing ample connectivity options for various network configurations. This adapter is equipped with several LED indicators for SPA status, per-port status, carrier and alarm, active, and loopback modes, making it easy to monitor the system's status at a glance. It supports Online Insertion and Removal (OIR), allowing for seamless upgrades and replacements without disrupting network operations. The SPA-4XOC3-POS-V2 is designed with a focus on network management, featuring support for RFC 2558 MIB for SONET/SDH and Simple Network Management Protocol (SNMP), enabling efficient network monitoring and management. The hardware dimensions are compact, with a height of 0.8 inches, width of 6.75 inches, and depth of 7.28 inches, and it weighs just 0.75 lbs. Despite its small size, it requires 6 W of power for operation. The device operates within a temperature range of 5 °C to 40 °C and can be stored in temperatures ranging from -40 °C to 70 °C. It can function in a wide range of humidity levels, with operating relative humidity from 5% to 85% and storage relative humidity from 5% to 95%. The SPA-4XOC3-POS-V2 supports both local (internal) and loop-timed (recovered from the network) synchronization, along with pointer activity monitoring. Its payload mapping is based on POS with a 1 + X^43 self-synchronous scrambler, optimizing performance for high-speed networks. Safety is a priority with this device, adhering to standards such as UL 60950, CSA 22.2-No.60950, EN60950, IEC 60950 CB Scheme, ACA TS001, and AS/NZS 3260. It features a pluggable design, adhering to the I-Flex design philosophy, which emphasizes flexibility and scalability in network infrastructure. The SPA's optical modules are field replaceable, ensuring easy maintenance and upgrades.
  • LED Indicators for comprehensive status monitoring
  • RFC 2558 MIB and SNMP support for efficient network management
  • Field Replaceable SFP Optical Modules for easy maintenance
In summary, the Cisco SPA-4XOC3-POS-V2 is a versatile shared port adapter offering high-speed connectivity and robust network management features. Its compatibility with a range of Cisco routers, coupled with its compact form factor and support for advanced network protocols, makes it an essential component for modern networking infrastructures seeking reliability and scalability.
