WatchGuard compatible WG8585 Description

EdgeOptic's WG8585 compatible is a WatchGuard-coded version of the EdgeOptic 1.25G-SFP-550D multi-vendor 1000BASE-SX transceiver. It runs Gigabit Ethernet at 1.25 Gbps (IEEE 802.3z) and 1G Fibre Channel SW at 1.0625 Gbps over duplex multimode fiber, with an 850 nm VCSEL transmitter and a PIN photodiode receiver.

A 7.5 dB optical budget carries the link 550 m over OM2 multimode fiber (50/125, 500 MHz·km) and 275 m over OM1 (62.5/125). The module uses a duplex LC/UPC interface and supports DDM/DOM diagnostics for live readings of optical power, bias current and temperature. It operates across the 0 to 70°C commercial range, built to the INF-8074i SFP MSA, +3.3V supply, CE/RoHS, Class 1 laser safety.

WG8585 is WatchGuard's ordering code for this 1G SX SFP, documented in WatchGuard's Firebox hardware guides as a 1000Base-SX 850 nm multimode transceiver. It goes into Firebox appliances with 1G SFP ports, either built into the chassis or on a 1G SFP interface module; confirm your exact model and module against WatchGuard's published supported-transceiver documentation. EdgeOptic codes the module's EEPROM with WatchGuard-recognized identification data.

Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For ordering-code confirmation or platform questions, contact our sales team.

Frequently Asked Questions

Which WatchGuard Firebox appliances does the WG8585 SFP go into?

WG8585 is WatchGuard's code for a 1000Base-SX 850 nm multimode SFP, so it belongs in Firebox appliances with 1G SFP ports, whether those ports are built into the chassis or sit on a 1G SFP interface module. WatchGuard's WG-prefixed codes span several accessory types, so match the code to the port type before ordering: this one is the short-range multimode SFP, not an LX single-mode or copper part. WatchGuard publishes the supported-transceiver list per Firebox model in its own hardware documentation, so check your model and interface module there, or contact our sales team and we will confirm the fit.
