Finisar compatible FTLC1156RDPLA Description
EdgeOptic's FTLC1156RDPLA compatible is a Finisar-coded version of the EdgeOptic 100G-QSFP28-20 multi-vendor 100GBASE-LR4 20km transceiver. It is a QSFP28 module built to the 100G 4WDM-20 MSA (eLR4) specification, reaching 20km over duplex single-mode fiber with a 9 dB minimum optical budget. The four LAN-WDM channels sit at 1295.56, 1300.05, 1304.58 and 1309.14 nm and terminate on a duplex LC/UPC connector. The base FTLC1156RDPL is the 10km 100GBASE-LR4 part; this RDPLA variant is the 20km eLR4 module, so confirm the part number against the required link distance before deployment.
The 20km eLR4 reach depends on host-side RS-FEC RS(528,514) per IEEE 802.3bj. The 4WDM-20 MSA places that error correction on the host, so the target port must have RS-FEC enabled. The IEEE 802.3ba Clause 88 LAN-WDM lane plan covers the 10km LR4 baseline only; the 20km reach comes from the 4WDM-20 MSA, not from 802.3ba.
The transmitter uses an EML laser and the receiver a PIN photodiode. Per-lane launch power runs from −1 to +4.5 dBm, receiver sensitivity is −11 dBm per lane and the receiver overload point is +3.3 dBm. The module draws up to 3.5 W and operates across the 0 to 70°C commercial temperature range with full DDM/DOM diagnostics. Beyond 100G Ethernet at 103.125 Gbps, the chipset also carries 128G Fibre Channel (Gen 6, 112.2 Gbps) and OTU4 (112 Gbps), so the same part covers Ethernet, storage and OTN transport on supported host ports.
