FN-TRAN-QSFP28-SR Fortinet Compatible 100GBASE-SR4 QSFP28

EdgeOptic's FN-TRAN-QSFP28-SR compatible is a Fortinet-coded 100GBASE-SR4 version of the EdgeOptic 100G-QSFP28-100 multi-vendor QSFP28 transceiver, one universal short-reach module coded for a range of switch and firewall vendors. It runs 100G Ethernet over four parallel 850 nm VCSEL lanes at 25G each across multimode fiber, terminated on an MTP/MPO-12 (UPC) connector using 8 active fibers, 4 transmit and 4 receive. The transceiver port is female (unpinned); the patch cable is the pinned male side. Reach is 70 m over OM3 and 100 m over OM4, per IEEE 802.3bm Clause 95.

Optical specifications match the OEM module: a 1.9 dB average link budget, receiver sensitivity of −10.3 dBm per lane, NRZ modulation, and no FEC required at this reach. The transmitter uses VCSEL lasers at 850 nm; the receiver is a PIN photodiode. The reach figures assume standard multimode attenuation, so 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. DDM/DOM is supported, so the host can read live optical power, temperature, bias, and voltage. The module operates across the 0°C to 70°C commercial temperature range at 3.5 W 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 Fortinet-recognized EEPROM so it is accepted natively. Compatible with FortiGate appliances that have 100G QSFP28 slots. Confirm the specific appliance model and FortiOS version against the Fortinet transceiver documentation before deployment. The FN-TRAN-QSFP28-SR is a multi-purpose short-reach optic used for data center core interconnects and high-throughput firewall uplinks. Full optical specifications are on the datasheet below.
