Finisar compatible FTLC1151SDPL Description
FTLC1151SDPL is the multirate (S variant) version of Finisar's first-generation 100GBASE-LR4 QSFP28 transceiver. This module supports three protocols: 100G Ethernet at 103.125 Gbps, OTU4 at 111.81 Gbps, and 128G Fiber Channel (Gen 6) at 112.2 Gbps. This EDGE compatible module matches the original FTLC1151SDPL specifications and is built to the same MSA standards. It operates over duplex single-mode fiber at four LAN-WDM wavelengths (1295.56, 1300.05, 1304.58, and 1309.14 nm), reaching up to 10 km with a minimum optical link budget of 6.3 dB per IEEE 802.3ba.
The module uses EML transmitters and PIN photodiode receivers. In Ethernet mode, four lanes run at 25.78125 Gbps each for 103.125 Gbps aggregate. In OTU4 mode, lanes run at 27.95 Gbps each for 111.81 Gbps per ITU-T G.709. In 128GFC mode, the aggregate rate is 112.2 Gbps. DDM/DOM provides real-time readings of TX/RX optical power, laser bias current, temperature, and supply voltage. Maximum power consumption is 3.5 W from a single 3.3 V supply. Operating temperature range is 0 to 70 °C.
As a QSFP28 MSA-compliant module, the FTLC1151SDPL is compatible with platforms that accept third-party optics, including switches, routers, and storage networking equipment with QSFP28 ports. The module operates at the rate configured by the host port. For 128G Fiber Channel, it works in SAN directors and switches with 128GFC-capable QSFP28 interfaces.
The FTLC1151SDPL and FTLC1151RDPL share the same optical interface: same wavelengths, link budget, reach, and form factor. The difference is protocol support. The R variant handles 100G Ethernet only, while the S variant also supports OTU4 and 128G Fiber Channel. On a 100GE link, the S variant is fully interoperable with the R variant at the opposite end.
Our compatible FTLC1151SDPL is CE and RoHS certified, QSFP28 MSA-compliant, and conforms to IEEE 802.3ba and ITU-T G.709. Before delivery, every module undergoes optical parameter measurement, connector cleanliness inspection, and EEPROM data validation testing.

Frequently Asked Questions
What is the difference between FTLC1151SDPL and FTLC1151RDPL?
The FTLC1151SDPL (S variant) is a multirate module supporting 100G Ethernet, OTU4, and 128G Fiber Channel. The FTLC1151RDPL (R variant) supports 100G Ethernet only. The optical specifications are identical between the two. On a 100GE link, either module works and they are interoperable. For OTU4 or 128GFC links, both ends must use S-variant or protocol-capable modules.
Does the FTLC1151SDPL support 128G Fiber Channel?
Yes. The FTLC1151SDPL supports 128GFC (Gen 6 Fiber Channel) at 112.2 Gbps in addition to 100G Ethernet and OTU4. This makes it suitable for SAN environments that require 128GFC connectivity over single-mode fiber up to 10 km.
Is there a newer generation of the FTLC1151SDPL?
The FTLC1154SDPL (Gen 2) and FTLC1156SDPL (Gen 3) are the successors in Finisar's multirate LR4 line. All generations share the same optical interface and are interoperable on the same fiber link. Check the specific generation's datasheet to confirm 128GFC support, as protocol coverage may vary between generations.
Can I use the FTLC1151SDPL for Ethernet-only deployments?
Yes. The FTLC1151SDPL operates at the rate the host port is configured for. On an Ethernet port, it runs 100GBASE-LR4 at 103.125 Gbps. It is fully interoperable with the Ethernet-only FTLC1151RDPL on the opposite end of a 100GE link.
