Finisar compatible FTLC9558REUM Description

EdgeOptic's FTLC9558REUM compatible is a Finisar-coded 100GBASE-SR4 version of the EdgeOptic 100G-QSFP28-100 multi-vendor short-reach transceiver, one universal QSFP28 module coded for a range of switch and router vendors. It carries 100G Ethernet over four parallel 850 nm VCSEL lanes at 25G each across multimode fiber, with 8 active fibers, 4 transmit and 4 receive. The FTLC9558REUM is the pigtail-packaged form of the FTLC9558REPM: an attached multimode fiber pigtail terminated in an MPO-12 connector replaces the standard pluggable MPO receptacle. Reach is 70 m over OM3 and 100 m over OM4, per IEEE 802.3bm Clause 95.

Optical specifications include a 1.9 dB average link budget, receiver sensitivity of −10.3 dBm per lane, and NRZ modulation, with no FEC required at this reach. The transmitter uses 850 nm VCSEL lasers; the receiver is a PIN photodiode. OM4 supports the full 100 m while OM3 is rated to 70 m, with achievable distance depending on patch panels, splices, and connector cleanliness in the installed link. The pigtail carries 8 active fibers and terminates in an MPO-12 connector with factory-set polarity; confirm the pigtail polarity specification with the supplier when ordering for a specific installation. DDM/DOM is supported, so the host can read live optical power, temperature, bias, and voltage. The module operates across the commercial temperature range and is compliant with the QSFP28 MSA and SFF-8665. This is a 100G Ethernet short-reach optic; it does not carry Fibre Channel, OTN, or SONET traffic.

EdgeOptic codes this compatible with Finisar-recognized EEPROM, so it presents as the original module on host platforms that accept Finisar-coded optics; confirm the specific switch model and line card against the vendor transceiver compatibility matrix before deployment. The standard EdgeOptic build uses the pull-tab module form with a pluggable MPO receptacle; if your installation requires the attached pigtail assembly, our sales team can advise on sourcing. Typical roles include data center core interconnects, ISP aggregation, and mobile operator core networks.

Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For project pricing or technical consultation, contact our sales team.

Frequently Asked Questions

What is the difference between FTLC9558REUM and FTLC9558REPM?

They share the same Gen3 100GBASE-SR4 optical and electrical specification, but the packaging differs. The FTLC9558REUM is the pigtail build, with a multimode fiber pigtail permanently attached and terminated in an MPO-12 connector. The FTLC9558REPM is the standard pull-tab module with a pluggable MPO receptacle. Match the form factor your installation needs; for the attached pigtail assembly, contact our sales team.
