I have tested a variety of equipment as part of my FTTH enterprise. Active
Ethernet is where I’m still sitting because I’m not quite happy with some of
the PON hardware out there personally.
Yes active solutions provide more flexibility in one area but they are only
viable in dense environment

drivers work for an OC3 card. That went very badly and the whole lot was ripped
out again after a couple of years from memory.

You will never get 25 years out of this, I predict 6mos and then you rip it
completely and put in copper/IDFs.

Unfortunately management didn't want an apple to apple comparison. They
wanted a comparison to how it was spec'd out originally not how we
typically deploy it now. I don't think this is a deal breaker for my job,

We think it makes sense for cost reduction for semi rural or suburban aerial
distribution- reducing the fiber count to like. 12. Reduces costs dramatically
vs say a 288 count and all the splicing. (Ribbons are better)

Update your CV - It is not your responsibility to shoulder the stress of
your superiors' bad decisions, especia
The cost analysis was already done. The cost is around 10% less. The
implications are there is no redundancy, lacking capacity, costs were not
factored in for BBUs on every ONT like should have been spec'd out for
emergency phone lines, etc. After that was done management said to suck it

Ceiling tiles. There is a special ceiling tile that drops down that
maintains our 24 port ONTs that do PoE+ to our Cisco WAPs. It's most

That is correct. We are running SMF from our Datacenter to the end users

Hi Nick,

Working with that much fiber is expensive. Too much work at each splice
point. Huge inflexible cables. Expensive machinery to blow the fiber.
