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 Key Features • Integrated Variable Attenuation (VOA) option • Integrated Power Meter (OPM) option • Instrumentation grade performance • Ultra-low insertion loss • High repeatability • Low polarization dependent loss • High power handling • Dark fiber switching • Bi-directional operation • Protocol and bit rate independent • Ethernet, RS232 and GPIB options • Standard protocols: SCPI, TL1, SNMP 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® 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. Applications • Automated component test • Automated manufacturing test • Network span emulation • Systems verification testing • Centralized optical equipment sharing • Secure communication networks • Centralized PON/FTTH test capability • ROADM High performance optical switch solutions Packaging Information Performance Specifications Fiber Count Designator I K -100, -300, -400 Output Monitor or Absolute VOA -200, -500 Input & Output Monitor or Relative VOA -100, -300, -400 Output Monitor or Absolute VOA -200, -500 Input & Output Monitor or Relative VOA Insertion Loss @ 1550nm 1 <1.2dB <1.3dB <1.6dB Polarization Dependent Loss @ 0 dB attenuation <0.1dB <0.1dB <0.15dB Crosstalk <-70dB 1260-1625nm Wavelength Dependent Loss <0.3dB (C+L Band) Repeatability 6 <±0.05dB Return Loss >55dB 2 Switching Time Maximum Optical Power +24dBm Switch Lifetime 108 cycles Operating Temp (Normal) 19” rack mount 1 rack unit high <1.7dB 17-32 FC, SC or ST 19” rack mount 2 rack units high <0.15dB 33-64 All 19” rack mount 3 rack units high 45W Ordering Information The part numbering scheme for Polatis products is as follows: VST - x - 1- Operating Temp (Extended) - 5° to +55°C, <90% RH non-condensing Storage Temp (Normal) -40° to +70°C, <40% RH non-condensing Storage Temp (Extended) -40° to +70°C, <95% RH non-condensing Designed to meet EN60950 Qualification (Extended) Designed to meet Telcordia GR63 EN60950 VOA Performance Optical Attenuation Range VOA Resolution < 0.25dB 7 Output Stability @ 0dB 8 >40dB < ± 0.05dB OPM Performance Operating Wavelength Range 5 1290-1330nm + 1450-1625nm OPM Dynamic Range -30 to +24dBm 4 OPM Accuracy < ± 0.5dBm All parameters are measured excluding connectors at 1550nm and 20°C with an unpolarized source after thermal equalization unless stated. 1.
