Finisar compatible FTLC2151SDPL Description
EdgeOptic's FTLC2151SDPL compatible is a Finisar-coded QSFP28 transceiver for 100GBASE-ER4 Lite reach over single-mode fiber, with OTU4 dual-rate support on the same optics. The module covers 40 km of duplex SMF using LAN-WDM wavelengths 1295.56, 1300.05, 1304.58, and 1309.14 nm, terminated on an LC duplex connector.
The line rate envelope spans 103.125 Gbps for 100G Ethernet and 111.81 Gbps for OTU4 (G.709) transport, so the same FTLC2151SDPL drops into either a 100GE host port or an OTN line card carrying OTU4 traffic. This is the differentiator for the S-suffix Finisar variant: the FTLC2151RDPL R-suffix sibling is 100GE-only, while the SDPL adds OTU4 transport on the identical 40 km LAN-WDM optics.
Optical link budget is 22 dB with host FEC and 18 dB without FEC. Tx is an EML laser per LAN-WDM lane; Rx is an APD photodetector chosen for the ER reach class. DDM/DOM telemetry is supported per SFF-8636, surfacing per-lane temperature, voltage, bias current, Tx power, and Rx power for fault isolation. Operating temperature is 0 to 70 °C commercial, with 4.5 W maximum power on +3.3 V supply.
Typical deployments include ISP aggregation and metro backbone spans, mobile operator core links, dark-fiber leased-line builds, and data-center interconnect fibers where 40 km reach is needed and OTU4 transport may be required by the OTN equipment. EdgeOptic codes the transceiver EEPROM to match what the host platform reads from a genuine Finisar module, so the SKU enumerates and links without third-party-optic warnings on hosts that key off the Finisar vendor name and part number in the EEPROM. Hardware compliance covers QSFP28 MSA mechanicals per SFF-8665 and the SFF-8636 management interface, with CE and RoHS certification on the regulatory side. The module is hot-pluggable into any 100G QSFP28 cage that exposes the four LAN-WDM lanes at the host.
