VOA5 Series
Single Mode & Multimode Variable Attenuators
The VOA5-MM (multimode) and VOA5-SM (single-mode) are hand-held, field-rugged variable
optical attenuators suited for a wide range of fiber link certification and production test
applications. The VOA5 can be operated under local control (front panel keypad) or from a
PC via a serial link using the supplied PC software. The VOA5 offers high bi-directional return
loss and will maintain the set attenuation level when the unit is powered down.
The VOA5 is powered by (2) AA alkaline batteries or an AC power adapter. A NiCad
rechargeable battery pack is an option.
SVA1
Single Mode Variable Attenuator
The SVA 1 Single-mode Variable Attenuator advances fiber optic field testing by offering
superior performance in a low cost hand-held package. Utilizing a simplified, industry
accepted attenuation technique, the innovative design of the SVA 1 offers superior resolution
across the entire 60 dB dynamic range.
Intended for field testing during installation, new equipment turn-ups, or for performing
routine maintenance, the SVA 1 is a complete, easy to use attenuator. Its unique features
allow bi-directional signal transmission with no loss penalty.
The SVA 1 is available with a variety of connectors and reflectance options to better than 60
dB. With only two adjustments, COARSE and FINE, the SVA 1 is simple to understand and
operate. The SVA 1 is suited for all singlemode applications including Telco, LANs, WANs, Video,
and CATV.
