VOA & Power Meter Switch Tray
VST
Reconfigurable
VOA & Power Meter Switch Tray
The Polatis VST family of products offers an ideal integration
of optical switching, attenuation and power monitoring in a
single, compact package. This class of switch is unique to
Polatis and delivers significant cost savings for a highly
versatile tool with a single, easy-to-use interface.
The Reconfigurable option provides user-definable input
and output ports, providing unprecedented flexibility for
applications with changing needs. Users can create any
matrix up to the total fiber count, such that a 16x16 could
be reconfigured to a 1x31.
Ideal for test environments, the VST provides physical-layer
connectivity for sharing of high value equipment and
automation of test sequences in design verification for
manufacturing systems. Its instrument-grade performance
ensures the maximum signal fidelity, with ultra-high stability
and repeatability. VST integrated power meters permit rapid
trouble-shooting across the entire test set without patching
in separate meters.
The unique VOA function permits easy control of preset
maximum power levels to protect sensitive downstream
equipment.

All parameters are measured excluding connectors at 1550nm and 20°C with an unpolarized
source after thermal equalization unless stated.
1. Measured using a 3 patch-cord method as defined in TIA/EIA-526-14A
2. With APC connectors return loss >70dB without connectors
3. Switch will operate on dark fiber
4. Dynamic range for extended temperature is –20 to +24dBm
5. Calibrated range for optical power monitors; switch operable over 1260-1625nm
Partially populated VOA & OPM options also available. Call for details.
The performance characteristics of the switch trays
vary according to the fiber count and the selected
VOA and OPM options.
