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(R) technology
All Polatis products are based on the patented DirectLight beam-steering technology, setting the benchmark for reliable, high performance switching. Polatis also offers Reconfigurable port and Multimode optical switch systems, as well as a range of optical switch modules and standard backplane optical cards.

OPMAccuracy
All parameters are measured excluding connectors at 1550nm and 20C 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.
