Ciena B-720-1086-400 Line Card

Ciena B-720-1086-400 Line Card for the CN4200 family provides 10 GbE client interfaces and STM-64 transport on a single module that plugs into a CN4200 chassis. Designed for CN4200-based optical transport networks, this line card carries 10 Gigabit Ethernet services and STM-64 payloads within the same card, enabling high-capacity Ethernet connectivity alongside traditional SDH/SONET transport in carrier deployments. As a CN4200 line card, it is intended to extend existing CN4200 installations by adding 10 GbE endpoints and STM-64 trunking without requiring a separate interface module. The part number B-720-1086-400 is referenced in vendor catalogs as a CN4200 10GBE & STM-64 line card, underscoring its role in aggregating Ethernet traffic over STM-64 paths. In typical deployments, it supports backhaul links between urban aggregation points, interconnections between data centers, and service delivery scenarios where Ethernet traffic must be carried over STM-64 transport within the CN4200 platform. Installation and operation depend on using it within compatible CN4200 slots and adhering to the CN4200 subsystem’s guidelines for line-card insertion, slot power, and software/firmware requirements. This card represents a modular option for scaling CN4200 networks to accommodate higher Ethernet service density without replacing existing chassis, aligning with environments prioritizing Ethernet over SDH/SONET transport in a compact, integrated form factor.
