Dell (Force10) compatible Q28-100GESR4 Description
EdgeOptic's Q28-100GESR4 compatible is a Dell-coded 100GBASE-SR4 version of the EdgeOptic 100G-QSFP28-100 multi-vendor 100GBASE-SR4 transceiver, one universal short-reach module coded for multiple vendor platforms. It carries 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 and unpinned; the patch cable is the pinned male side. Reach is 100 m over OM4 and 70 m over OM3, 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 required at this reach. The transmitter uses 850 nm VCSELs; 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 through SFF-8636, so the host reads per-lane transmit power, receive power, and laser bias plus module temperature and supply voltage. The module operates across the 0°C to 70°C commercial range at up to 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.
Q28-100GESR4 is Dell's ESR4 ordering code, an extended-reach 850 nm multimode build rated up to 300 m on OM4; this EdgeOptic compatible covers the standard 100GBASE-SR4 100 m application. The part is used on Dell PowerSwitch S-series and Z-series switches with 100G QSFP28 ports, and EdgeOptic codes it with Dell-recognized EEPROM so the host accepts it on supported platforms. Confirm the specific switch model and line card against the Dell compatibility matrix before deployment.

Frequently Asked Questions
The Dell Q28-100GESR4 is the ESR4 extended-reach variant. Will the EdgeOptic compatible run a 300m span?
The Dell Q28-100GESR4 is the ESR4 ordering code, rated up to 300 m on OM4. This EdgeOptic compatible is built to the standard 100GBASE-SR4 specification, so it is qualified for the 100 m OM4 / 70 m OM3 application rather than the full ESR4 distance. Use it where the link sits inside the SR4 range. If a deployment requires the longer ESR4 reach, contact our sales team and we will spec an extended-reach optic to the measured span loss.
