Ciena XCVR-C70D47 SFP Optical Transceiver Module

XCVR-C70D47 is a 10 Gbps CWDM SFP+ optical transceiver for single-mode fiber that uses a 1470 nm CWDM transmission wavelength and a duplex LC connector. It supports up to 70 km on SMF and includes Digital Optical Monitoring (DOM) for real-time visibility into transmit power, temperature, and other key metrics. Marketed as part of Ciena’s XCVR family and commonly listed as XCVR-C70D47-C, this module is designed for CWDM deployments between network devices such as switches and routers, enabling longer-reach 10G links in enterprise, data-center interconnects, and metro networks. The SFP+ form factor and 1470 nm CWDM channel make it suitable for point-to-point links that require scalable 10G over longer distances without DWDM. Verified listings identify this part as a 10G SM SFP+ optic with LC connector and 70 km reach, and note DOM support, aligning with CWDM applications over single-mode fiber.
