WatchGuard WG8583 Compatible 10G SR SFP+

WatchGuard Firebox appliances with SFP+ expansion bays accept the WG8583, a 10GBASE-SR SFP+ transceiver for multimode fiber uplinks. The Firebox M Series (M290 through M690) all reference this SKU. Typical deployment scenarios include 10G connections between the security appliance and aggregation switches, inter-appliance HA links, or uplinks from the firewall to the data center switching fabric.

EdgeOptic's compatible WG8583 runs on the 10G-SFP-300 platform with EEPROM coded for WatchGuard recognition. Transmitter is an 850 nm VCSEL, receiver a PIN photodiode, giving a minimum 6.1 dB link budget. Reach is 300 m on OM3 and 400 m on OM4 multimode fiber through a duplex LC/UPC connector. The module supports data rates from 1.25 to 10.3125 Gbps, so it also handles GbE links on dual-rate ports. IEEE 802.3ae compliance covers the 10GBASE-SR standard, and the SFF-8431/8432 mechanical and electrical design follows the SFP+ MSA.

DDM telemetry reports TX power, RX power, laser bias, temperature, and supply voltage. These readings are accessible through the WatchGuard management interface on platforms that expose transceiver diagnostics. Operating temperature is rated at 0 to 70 °C, and the module carries CE/RoHS certification. Each unit passes EdgeOptic's production QC before dispatch, with particular attention to EEPROM field accuracy against WatchGuard's expected vendor and part number identifiers.

Security appliances often sit in environmentally controlled server rooms, but the 0-70 °C commercial rating is the standard commercial operating range for SFP+ modules. When replacing OEM modules mid-lifecycle, the compatible WG8583 can operate alongside original WatchGuard optics on opposite ends of the same 10G link without optical compatibility concerns.
