Ciena F10-T90-TN B-720-1086-300 Optical Transponder

The Ciena F10-T90-TN B-720-1086-300 Optical Transponder is a transport-grade module that carries client signals at 10 Gigabit Ethernet and STM-64 over a DWDM optical link. Identified by part number B-720-1086-300, it belongs to Ciena’s F10-T90-TN family and is designed to bridge 10GE/STM-64 client traffic to the optical transport layer. The device supports OTU2 with forward error correction (FEC) for network signaling and is configured for an ITU-T 50 GHz channel grid, aligning with standard DWDM spectral plans. In practice, this transponder converts and multiplexes client signals onto a dedicated optical wavelength, enabling interconnection between edge devices or line equipment across metropolitan or long-haul networks. The combination of 10GE and STM-64 client interfaces, OTU2 FEC-enabled transport, and 50 GHz ITU grid makes it suitable for deployments that require reliable high-rate connectivity while fitting within established spectral allocations. With the explicit part number and the described capabilities, network engineers can verify compatibility within Ciena’s transport portfolio and plan integrations that demand OTU2-based signaling, robust client support, and precise channel placement on a legacy or evolving DWDM infrastructure.
