FG-TRAN-QSFP28-SR4 Fortinet Compatible 100GBASE-SR4 QSFP28 Transceiver

EdgeOptic's FG-TRAN-QSFP28-SR4 compatible is a Fortinet-coded version of the EdgeOptic 100G-QSFP28-100 multi-vendor 100GBASE-SR4 transceiver, one universal short-reach QSFP28 module coded for multiple vendor codes. 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, so a transceiver-to-transceiver link uses a male-to-male Type B cable. 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, NRZ modulation, and no FEC at the optical PMD level. 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. DDM/DOM is supported, so the host can read live per-lane optical power and bias along with module temperature and voltage. The module operates across the 0°C to 70°C commercial temperature range and complies with the QSFP28 MSA, SFF-8636, 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. It works on FortiGate and FortiSwitch platforms with 100G QSFP28 ports; verify the specific model and FortiOS release against the Fortinet compatibility matrix before deployment. Typical roles include data center core interconnects, ISP aggregation, and mobile operator core networks.
