Ciena XCVR-S40V55 Compatible 10GBASE-ER SFP+ 40km

EdgeOptic's XCVR-S40V55 compatible is a Ciena-coded version of the EdgeOptic 10G-SFP-40 multi-vendor 10GBASE-ER SFP+ transceiver. It runs 10 Gigabit Ethernet to IEEE 802.3ae over a duplex single-mode fiber pair, with the EEPROM programmed so Ciena platforms read the module as a recognized transceiver. XCVR-S40V55 is the bare grey-optic ordering code in Ciena's XCVR naming convention. The suffixed XCVR-S40V55-CWxx variants are fixed-wavelength CWDM channel parts; this part is the standard 1550 nm grey ER module, so confirm the exact suffix on the ordering line before substituting.

The optical interface uses a 1550 nm DFB laser transmitter and a PIN photodiode receiver. Transmit power runs from −1 dBm to +4 dBm, receiver sensitivity is better than −16 dBm, and receiver overload is 0 dBm, which gives a 15 dB link budget for reach to 40 km over single-mode fiber. The module carries an LC duplex connector and operates across the 0 to 70 °C commercial temperature range on a +3.3 V supply. Distance is an indicative figure derived from the link budget and typical cable attenuation, so the achievable span depends on the fiber plant, splice loss, and connector count on the route.

Built to the SFP+ form factor, the module follows the SFF-8431 host electrical specification and reports digital diagnostic monitoring per SFF-8472, so transmit power, receive power, laser bias, temperature, and supply voltage are readable from the host. Multi-rate operation spans 1.25 to 11.32 Gbps, which covers 1GE and 10GE Ethernet alongside STM-64 SONET/SDH transport. Ciena 6500, Waveserver, and other packet-optical transport platforms handle SONET/SDH line services, so the STM-64 mode is applicable in those deployments. Confirm the supported rate for the specific line card and port against Ciena's transceiver compatibility table for your platform and SAOS release.

Common deployments include service provider aggregation and backbone links, mobile backhaul, and data center site interconnect where a 40 km grey-optic ER span is needed. The module is CE marked, Class 1 laser rated to IEC 60825-1 and FDA standards, and RoHS compliant.
