Voa & power Meter switch tray
Vst
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.
Ideal for test environments, the VST provides physical-layer
connectivity for sharing of high value equipment and for
automation of test sequences in design verification and
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 attenuation for trimming power, or of
preset maximum power levels to protect sensitive
downstream equipment.
Users may fully configure all ports for power meter and VOA
functionality, or choose from sub-populated options. Power
meter options include Input and/or Output detectors, while
optical attenuation options include both Relative attenuation
(power drop across switch) or Absolute attenuation (fixed
output power).
The VST is available in both symmetric (NxN) and
asymmetric (MxN) port configurations, provided in a
standard 19” rack mount enclosure.
Directlight
®

OPM Accuracy
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.
6. At zero attenuation.
7. When output power is within OPM dynamic range.
8. For stability at various levels of attenuation please contact Polatis for further details.
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.
