English term or phrase: back reflection

Does anyone there master Optic Fiber transmission, equipment, terminology, etc?

I’m dealing with a monitoring system – wire fences, cameras, etc. – to be installed in a farm in Mato Grosso, owned by an Arab potentate. I have access to some specialized dictionaries but only English-English. I know what they mean but I am not sure how to translate it. Could someone help me, please?

Equipment to be installed:

PM Fused Coupler = Acoplador ligado à PM (Phase Modulation = Modulação de Fase)?
Acoplador PM Fundido?
Ou o quê?

Polarization Maintaining Coupler (PMC) (built by using super fusing tapering technique). The PMC can be used to split high power linear polarized light into multiple paths without perturbing the linear state of polarization.
PMC parametres: **Back Reflection > 45 dB**
Achei: reflexão traseira

Communication plate specifications: … Sink current 15 m A Source current 15 m A
Achei: sink current – refer to: current sink = dissipador atual (the maximum current that data acquisition output channels can dissipate.
Achei: sink current = coletor de corrente

FOG Based Strap-down Inertial Navigation/Hybrid Navigation System = Sistema de Navegação por Inércia Rígido/Navegação Híbrida Baseado no FOG

FOG Based Strap-down Inertial Attitude Reference System = Sistema de Atitude por Inércia Rígido baseado no FOG

Notes to answerer

Asker: Amigo, pensei que poderia ser isto, mas veja bem, a página que vc deu de referência trata de reflexão luminosa. O problema é que aqui a medida é dB. Aí está minha dúvida. Trata-se de uma reflexão sonora.
