Finisar compatible FTLX6873MNC Description

EdgeOptic's FTLX6873MNC compatible is a Finisar (now Coherent Corp.)-coded tunable 10G DWDM SFP+ for 80 km links over single-mode fiber. The MNC suffix marks this as the extended-temperature member of the FTLX6873 base family, the sibling to the standard-temperature FTLX6873MCC. Engineers select the MNC variant when the deployment environment, telecom outdoor cabinets, hardened cell-site enclosures, or wide-temperature aggregation shelves, demands the extended thermal envelope the OEM rates this part for.

Specs follow the EdgeOptic root: C-Band ITU 50 GHz grid, Channels 17 to 61 (89 channels, 1528.38 to 1564.68 nm), tunable per SFF-8690. Launch power −1 to +4 dBm, RX sensitivity −23 dBm, RX overload −6 dBm, optical budget 23 dB, dispersion tolerance 1600 ps/nm. Multi-rate from 1.25 to 11.32 Gbps covers 10G Ethernet ZR, 10G and 8G Fibre Channel, STM-64/OC-192, and OTU2/OTU2e/ODU2 OTN line side. Operating temperature 0 to 70 °C, +3.3 V supply, DOM/DDM via SFF-8472, CE/RoHS/Class 1 laser, SFF-8431 and SFF-8432 mechanical. The 50 GHz channel grid contains every 100 GHz channel center frequency, so EdgeOptic's compatible substitutes cleanly for both 50 GHz and 100 GHz OEM-spec deployments on existing C-Band mux/demux infrastructure.

OEM Finisar/Coherent tunable DWDM SFP+ modules in this class ship across host platforms as Cisco DWDM-SFP10G-C/C-S, Juniper SFPP-10G-DT-ZRC2 and SFPP-10G-CT50-ZR, Arista SFP-10G-DZ-T, Ciena XCVR-T80W01, HPE JL250A, Brocade 10G-SFPP-ZRD-T, Nokia 3AL82017AA, and similar tunable line cards. Channel selection is programmed by the host via the SFF-8690 2-wire serial interface, so verify the chassis/line card supports software tuning before deployment.

Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Made to order with a 2-week lead time and lifetime warranty included. For volume orders, channel-plan staging, or platform-specific coding requests, contact our sales team.

Frequently Asked Questions

What is the difference between the FTLX6873MNC and the FTLX6873MCC?

The MNC suffix marks Coherent's extended-temperature variant of the FTLX6873 base, while MCC is the standard-temperature commercial variant. Both share the same C-Band 80 km reach class and SFP+ form factor; the OEM rates the MNC for a wider operating temperature envelope. EdgeOptic's compatible operates over the standard 0 to 70 °C range. Engineers replacing an OEM FTLX6873MNC in a hardened or telecom-cabinet deployment should confirm the deployment temperature falls within the standard envelope before substituting; otherwise specify an industrial-temperature equivalent.

Will the FTLX6873MNC work on existing 100 GHz C-Band mux/demux infrastructure?

Yes. EdgeOptic's compatible is a 50 GHz tunable module on the C-Band ITU grid, and the 50 GHz grid contains every 100 GHz channel center frequency. The host programs the active channel via the SFF-8690 2-wire serial interface, so the same physical module can be tuned to a 100 GHz channel slot for cross-connect into an existing 100 GHz mux/demux, or to a 50 GHz channel for a tighter-spaced plan. Confirm the active channel selection on the host CLI matches the wavelength expected at the mux/demux port.
