All, I am chairing an effort in the IEEE 802.3 Ethernet Working Group to understand bandwidth demand and how it will impact future Ethernet needs. This is exactly the type of discussion i would like to get shared with this activity. I would appreciate follow-on conversations with anyone

Can't reccomend Flexoptix[1] enough. Great service, fast shipping, and you only need to maintain one stock of optics even if you use kit from different vendors. FS.com are the go-to for bulk purchases of pre-coded optics on a budget: a few more cot deaths than most, but they're cheap and in

Thanks to everybody that recommended Fiberstore and Flexoptics. Unfortunately Fiberstore is what led me to ask about alternative suppliers. Fiberstore actually ships in their Bidi SFPs from Asia and lead times are one to two weeks. Flexoptics is actually worse with 4-6 weeks after ordering.
