MODEL V720 ELECTRICAL / OPTICAL CONVERTER VME MODULE

The V720 is a six-channel logic-level electrical-to-optical converter, packaged as a single-width, 6U VME module. It may be used with compatible Highland optical receiver modules for fast, low-jitter, EMI-proof distribution of pulses, triggers, and precision timing signals.

Six channel logic-level electrical-to-optical converter Accepts most common electrical logic levels Three versions available: 850 nm, 1310nm, and 1550 nm Outputs 1 mW into 62/125 fiber or 9/125 fiber Propagation delay below 2 ns Jitter below 5 ps RMS Flexible input switching allows channels to share inputs for single-in/multiple-out fanout applications Usable in a VME rack, or standalone with available external power supply.

INPUT User-switchable per channel for logic level, normal/invert, and hi-Z/50-ohm terminated. Levels are TTL, NIM, ECL, and adjustable. Available with SMA, SMB, or Lemo connectors. Channels may be clustered to allow each electrical input to drive up to six optical outputs. OUTPUT V720-1 version- 850 nm: 1 mW optical power into 62/125 micron multimode optical fiber. V720-3 version-1310 nm. 1mW optical power into 9/125 micron singlemode optical fiber V720-5 version-1550 nm: 1mW optical power into 9/125 micron singlemode optical fiber Standard fiber connectors are ST. TIMING Propagation delay below 2 ns. Jitter below 5 ps RMS. Bandwidth DC - 1 GHz min. GATE One common electrical GATE input may be used to enable/disable all lasers. Logic level, polarity, and termination are user selectable. ENABLE A front panel SAFE/ENABLE toggle switch allows power to be removed from all lasers. POWER The module receives power from the VME backplane; it does not connect to the VME data bus, and passes all grant signals. The V720 may be used standalone with the optional model J190 power supply.
