Ciena F10EP-T90-TN-720-1086-401 Optical Line Card

The Ciena F10EP-T90-TN-720-1086-401 Optical Line Card is a 10 Gigabit Ethernet line card (model B-720-1086-401) that carries a 10GE STM-64 client interface mapped to OTU2 transport with Forward Error Correction. This module is built to operate in Ciena’s optical transport platforms, delivering reliable 10 Gb/s services over OTU2 transport with FEC on a 50 GHz card. The F10EP-T90-TN designation identifies this specific unit in Ciena’s line-card family; the 720-1086-401 numbering aligns with the hardware revision. Typical deployments include service-provider networks that require scalable, high-capacity transport of customer traffic, with OTU2 framing and FEC to enhance error resilience across longer links. Because this is an Optical Line Card, it plugs into compatible chassis within Ciena’s platform ecosystems, enabling integration with other line cards and network elements to form a multi-service transport fabric.
