Finisar compatible FTL4C1QE1C Description
EdgeOptic's FTL4C1QE1C compatible is a Finisar-coded version of the EdgeOptic 40G-QSFP-10 multi-vendor 40GBASE-LR4 transceiver. It replaces the Finisar (Coherent) FTL4C1QE1C in 40GBASE-LR4 Ethernet links, matching the original optical interface and host electrical specification.
The module runs four CWDM lanes at 1271, 1291, 1311 and 1331 nm, multiplexed onto a single duplex LC over single-mode fiber for reach up to 10 km. A DFB laser drives each lane and a PIN photodiode receives, with per-lane launch power between −6 dBm and +3 dBm and receiver sensitivity of −12.6 dBm per lane. The 6.6 dB link budget covers a standard 10 km G.652 span with margin. Digital optical monitoring reports temperature, supply voltage, bias current, and per-lane optical power.
The FTL4C1QE1C is the Ethernet-focused part in the Finisar QSFP+ LR4 family. The QM variants, FTL4C1QM1C and FTL4C1QM2C, are the OTU3 multirate versions. This page covers the FTL4C1QE1C Ethernet LR4 application. The EdgeOptic 40G-QSFP-10 platform that this compatible is built on also covers OTU3 multirate variants; if a deployment needs OTU3 transport on an OTN-capable platform, contact our sales team to specify the right variant. For the exact protocol scope of the original part, verify against the Finisar datasheet.
This optic is built to the IEEE 802.3ba Clause 87 40GBASE-LR4 standard and the QSFP+ MSA. It operates from 0 to 70 degrees C. Because Finisar optics appear in approved-optics lists across many switch and router brands, confirm host compatibility against the equipment vendor's transceiver matrix for your platform.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For volume pricing or qualification support, contact our sales team.
Frequently Asked Questions
What is the difference between FTL4C1QE1C and FTL4C1QM1C?
The FTL4C1QE1C is the Ethernet-focused 40GBASE-LR4 part, while the FTL4C1QM1C and FTL4C1QM2C are marketed as OTU3 multirate versions. They share the same four CWDM lanes, 10 km reach, and duplex LC. For 40GBASE-LR4 Ethernet links the QE part is the match. EdgeOptic's compatible covers the QE Ethernet use case; for OTU3 multirate deployments on an OTN-capable platform, contact sales to confirm the correct variant. Verify the original part's exact scope against the Finisar datasheet.
