HPE JD581A 1 x Port OC-3c/STM-1C POS Flexible Interface Controller Module (FIC) for MSR Router Flexi...

Product Description

The HPE JD581A is a Flexible Interface Controller (FIC) module designed for integration into HPE MSR (Modular Services Router) series routers. It provides a single port that supports Packet over SONET/SDH (POS) connectivity at the OC-3c/STM-1C rate, which is approximately 155.52 Mbps. POS is a technology that allows IP packets to be transmitted directly over SONET or SDH networks, which are high-speed synchronous optical networks commonly used for backbone telecommunications. This module is crucial for establishing Wide Area Network (WAN) connections that require high-speed, reliable, and synchronous serial data transmission. It enables routers to connect to carrier networks that utilize SONET/SDH infrastructure, often for high-capacity data transport. The 'c' in OC-3c/STM-1C typically refers to channelized interfaces, meaning the single high-speed link can potentially be subdivided into smaller channels, although the primary function here is high-speed POS transport. The JD581A is part of HPE's flexible module architecture, allowing network administrators to customize their MSR routers with the specific interface types needed for their network topology. This module is particularly relevant for service providers and large enterprises that need to connect to or extend their networks over existing SONET/SDH infrastructure, ensuring high-performance data delivery for critical applications.
