F5 F5-UPG-SFP28-SR Compatible 25GBASE-SR SFP28 Transceiver for rSeries

EdgeOptic's F5-UPG-SFP28-SR compatible is an F5-coded version of the EdgeOptic 25G-SFP28-100 multi-vendor 25GBASE-SR SFP28 transceiver, built for the F5 BIG-IP rSeries appliance line. The module matches the F5-UPG-SFP28-SR field upgrade kit specification published in F5 transceiver techdocs, delivered as a short-reach 25 Gigabit Ethernet optic over multimode fiber for rSeries SFP28 ports. The UPG prefix is consistent with F5's field upgrade accessory naming, indicating a module shipped separately from the chassis rather than bundled at time of delivery.

The 850 nm VCSEL transmitter and PIN photodiode receiver deliver TX optical power of −5 to +2.4 dBm, RX sensitivity better than −10.3 dBm, and a 5.3 dB link budget. Reach is 100 m on OM4, 100 m on OM5, and 70 m on OM3 multimode fiber with an LC/UPC duplex connector. The module is IEEE 802.3by Clause 112 compliant and supports RS-FEC per Clause 91 (RS(528,514)) when enabled by the host port. Line rate is 25.78125 Gbps for 25GBASE-SR. The 28.1 Gbps figure that appears in some reseller listings refers to the SFP28 electrical SerDes maximum defined by SFF-8402, not the IEEE 802.3by line rate of this module.

Electrical interface follows SFF-8431 and SFF-8432 for the SFP28 cage. Digital diagnostics are SFF-8472 compliant, exposing per-port temperature, supply voltage, TX bias, TX power, and RX power through F5OS platform telemetry and standard SNMP polls. The EdgeOptic compatible draws 0.3 W typical power consumption, compared with the OEM 1.0 W spec listed in F5 transceiver techdocs, a measurable thermal saving when an rSeries chassis is populated across all SFP28 cages. The hot-swappable cage operates across the 0 to 70 C commercial temperature range.

Platform scope is rSeries. F5 techdocs list the F5-UPG-SFP28-SR for BIG-IP r2000, r4000, r5000, r10000, and r12000-DS chassis running F5OS; verify against F5 support documentation for your platform and software release before procurement. The rSeries SFP28 port does not negotiate down to 10G with an SFP+ module inserted; 25G optics are required for link-up on these ports. Legacy iSeries platforms expose SFP+ 10 Gigabit ports rather than SFP28 cages and are out of scope for this module.

F5 optics policy scopes F5 TAC support to F5-branded optics; third-party optics may operate in the port but F5 TAC will request replacement before troubleshooting a link fault. EdgeOptic's F5-coded EEPROM presents the module with the F5-UPG-SFP28-SR identity so F5OS accepts it at link-up without raising an unsupported-optic event. For rSeries link aggregation groups and high-availability pair commissioning, FEC and auto-negotiation settings must match at both ends; consult F5 support documentation for the FEC profile applied on rSeries 25G ports under your TMOS or F5OS release.
