Re: [nznog] Fibre circulators?

15 Jan 2014

      Thanks to everyone who replied. The Hoff has put me in touch with one of
the guys at gigalight, and I'm going to try and get some kit in to play
with before subjecting customers to it. I'll catch you in a couple of weeks
& share a beer and hopefully have something to show for it by then.

In this case it was LCA on all of the circulators and duplex LC on the
active equipment.
This was a pretty special case what we were doing here. But just figured
I'd chime in that my experience with circulators hasn't been great so far
and I seem to have similar issues to Mike.

Does that still happen if you use angled connectors? It shouldn’t..

Does anyone recommend a supplier for fibre circulators, preferably
with LC connectors? I'd be keen to hear anyone's experiences/horror stories
with them if you're willing to volunteer them.
At first glance, they seem like a nifty idea.
In my experience they end up being a lot more hassle than they’re worth
(finding somewhere to locate them in a rack, especially when that rack
isn’t yours; optics that launch a little bit too bright or receive a little
bit too dim resulting in ports standing up to themselves when the line side
of the circulator is disconnected), especially with availability of single
fibre optics up to 10Gbps.
I'll 2nd what Mike says here. When they work they work really well. The
problem is that when things get slightly strange you can still have a port
being up but you then have what you're advertising out being reflected
back. When every MAC you send out a port is advertised back at that port
then "interesting things happen".
