VOA5 Variable Fiber Optic Attenuator
The Noyes VOA5 from AFL Telecommunications is a handheld variable optical attenuator
suited for a wide range of fiber link certification and production test applications. Two
models are available, the VOA5-MM multimode and the VOA5-SM single mode model. The
VOA5 attenuator offers high bi-directional return loss and will maintain the set attenuation
level when the unit is powered down.
Input/output ports of the VOA5 are equipped with tool-free removable adapters to allow
the output connectors to be inspected and cleaned. The VOA5 is powered by two (2) AA
alkaline batteries or an AC power adapter. A NiCad rechargeable battery pack is available
as an option.
