Allied Telesis B-AT-SPFX/2-90 network transceiver module Fiber optic 100 Mbit/s SFP

Product Overview

AI-generated summary

At £74.47 ex-VAT, this Allied Telesis SFP is the kind of “swap-in and forget” part you buy when you’ve already got Allied Telesis kit and you just need the optics to behave reliably. If you’re maintaining an Allied Telesis switch where the optics are known-good within that ecosystem, it’s solid value—much less hassle than gambling on cheaper compatible modules that can be flaky with optics/DOM handling, link negotiation, or vendor firmware quirks.

That said, I’d only buy it if you’re certain it matches your switch’s expectations and the fibre run you’ve got is appropriate. If you’re building a new setup with unknown compatibility (or you’re trying to standardise across mixed brands), I’d pause—SFPs are rarely “universal” in practice, and one misstep can turn a quick replacement into troubleshooting time. For IT teams doing routine maintenance on Allied Telesis networks, it’s a sensible, cost-effective choice. For mixed-vendor environments, I’d either confirm compatibility in advance or consider a module with stronger cross-platform support.
