StarTech.com HPE J9151A Compatible SFP+ Module - 10GBASE-BX - 10 GbE Gigabit Ethernet BiDi Fiber (SMF)

Product Overview

AI-generated summary

For £20.83 ex-VAT, this is the kind of SFP+ that makes sense if you’re doing routine network maintenance and just need a link to come back up fast. StarTech’s “compatible” modules are generally fine for day-to-day use in properly set up environments, especially when the switch already supports the optics format you’re matching (SMF, BiDi, 10GbE). If you’ve got an HPE switch in a rack and you’re replacing a failed optical without wanting to pay the “brand-tax,” this is a sensible, cost-controlled option.

That said, I wouldn’t buy these blindly unless you’ve confirmed the exact requirements for your install (which direction/wavelength pair you need for BiDi, and what your existing link is expecting). BiDi optics are easy to get wrong, and when they’re mismatched you’ll see link instability or no link at all—so the savings only matter if you know you’re buying the right type. Also, if you’re building something mission-critical with tight change-control, it’s worth validating compatibility with your specific HPE model and firmware before relying on it at scale. For straightforward spares and repairs, though, it’s good value.
