Finisar compatible FTLC1157RGPL2-1Y Description
EdgeOptic's FTLC1157RGPL2-1Y compatible is a Finisar-coded CWDM4 QSFP28 version of the EdgeOptic 100G-QSFP28-2.1 multi-vendor 100G CWDM4 2km transceiver. Finisar (now Coherent Corp) lists FTLC1157RGPL2-1Y as a qualification variant of the FTLC1157RGPL2 within the FTLC1157 CWDM4 2km QSFP28 product line, sold as a general-purpose optic for system integrators and data center hosts that require the FTLC1157RGPL2-1Y ordering reference for sparing or bill-of-materials alignment.
The module runs four CWDM channels on the 1271, 1291, 1311, and 1331 nm wavelength plan defined by the CWDM4 MSA and ITU-T G.694.2, with NRZ modulation across each lane. Output uses a duplex LC connector and supports 2 km links over G.652 single-mode fibre. The optical front end uses DML DFB transmitters and PIN receivers, with host-side FEC supported per the CWDM4 MSA Technical Specification. Digital diagnostics report TX power, RX power, bias current, supply voltage, and temperature per SFF-8636.
The FTLC1157RGPL2-1Y covers 100 Gigabit Ethernet at 103.125 Gbps as a general-purpose CWDM4 MSA optic for 100GBASE-CWDM4 host ports. The EdgeOptic 100G-QSFP28-2.1 family additionally supports OTU4 (112 Gbps) and 4x32G Fibre Channel (112.2 Gbps) variants for OTN transport and SAN deployments. Those rates ship as separate part numbers, so for OTU4 or Fibre Channel coding contact our sales team.
FTLC1157RGPL2-1Y is a Finisar ordering code within the broader FTLC1157 CWDM4 2km QSFP28 product line. Because Finisar supplies optical components to multiple network equipment vendors, this part number circulates through OEM bills of materials and spares channels rather than locking to a single chassis family. Engineers ordering against the FTLC1157RGPL2-1Y reference are typically building or maintaining 100GBASE-CWDM4 hosts that accept any CWDM4 MSA compliant QSFP28.
FTLC1157RGPL2-1Y is a qualification variant of FTLC1157RGPL2 in Finisar's catalog. The -1Y suffix maps to a different qualification tier in Finisar's naming convention, so the two part numbers are not always interchangeable on a given host bill of materials. The base FTLC1157RGPL ordering code is a separate variant in the same three-part FTLC1157 cluster. Match the exact ordering code on the host BOM when commissioning a replacement, and confirm with EdgeOptic sales if the host catalog lists a different suffix than what is being installed.
The module is QSFP28 MSA SFF-8665 compliant, aligned with the CWDM4 MSA Technical Specification, and RoHS-6 compliant. DOM/DDM reporting follows SFF-8636 for monitoring TX power, RX power, bias current, supply voltage, and temperature during commissioning and ongoing link operation.
