Thanks for your comments
I'm not sure why you think we support only 850 nm.
As referenced in post, I'm looking for a 1300nm multimode SFP , the only multimode SFP offered by Cambium as you quite accurately rightly in the same post is the - 1000BASE-SX optical SFP for multimode on 850 nm wavelength (C000065L009) that operates in 850nm not 1300nm.

We're not aware of any optical SFP modules that support more than one data rate, and the modules we supply only support gigabit operation. If you can identify some multi-rate optical SFP modules we'd be happy to investigate further. Also, if you really need 100 Mbit/s operation on fiber, you're welcome to submit a feature request.
As you point out, there are many different gigabit optical SFP modules on the market. Whilst they appear similar, they are not always interchangeable. We have tested the parts that we supply to be certain that problems will not arise in operation. We think this is an effective way to support our customers. Other SFP modules in the same format might well work, but we can't provide much support if you use other parts.
The GLC-FE-100FX-RGD work in both fast ethernet and gig ports whilst running 100base FX and the GE variant works in gig ports, have tried, ive got a dozen different SFP's on hand to trial and purchased a few more yesterday.
page 2-42 of the user manual have them listed... I've never seen a 5km tall tower, but someday it might happen...
and as cambium said, you can try other SFPs other brands do work, they just can't guarantee reliability... like every other vendor out their says.
Cambium don't actually say, "try other SFP's" they lock down / licence SFP ports and then sell only 3 SFP options, 2 of which being Fiber. I don't have a problem with paying for the 'licence' but need more supported SFP's
Yes, Towers might not be 5km tall, but if that's all you've got to worry about you are sorted. Radios are often 5km + from existing networks,
I do not have a R+D engineering TEAM on hand that a tech company the size of Cambium would have many divisions, I'd think with the latest 5G fiber to the radio networks being deisnged that Cambium would be all over the use of fiber to the radio - fiber SFP ports - but instead Cambium offer 2 fiber SFP's. I understand a company like CISCO will only support CISCO SFP's but consider the range they offer, its closer to 50 than 2.
I'm happily putting my own time and money into researching this as Cambium haven't, or they have and don't want to put the info out there.
I've bought 2x PTP650's just for testing, I've bought a bunch of switches and SFP's to emulate what I'm trying to create. As Cambium couldn't assist with info they have sent me a licence yesterday to test a unit so getting somewhere and hopefully it works but the limitation of what is sold / supported is a joke SFP wise, the PTP650 radio's are brilliant otherwise.
