Re: Angled Polish Connectors and DWDM

[Daniel Griggs <daniel () fx net nz>]

We have been using APC connectors on our DWDM deployments now for about 5
years and have had no issues with it at all.

Additionally, last year we engaged several DWDM system providers  and one
of the questions we asked them was, did they know of any issues with APC
connectors especially with regard to dual polarization systems. All vendors
came back with having no issues with APC connectors.
