Overview
The J724 is a compact standalone electrical-to-optical converter. It accepts a digital logic level input and provides a fast fiber-coupled laser drive.
Input threshold is user-settable from -4.0 to +5.0 volts, and termination is selectable to be 50 ohms or 1K.
Model J724-1 includes an 850 nm VCSEL laser with ST connector, suitable for driving 62/125 micron multimode fiber. It can drive the J730-1 single-channel O/E converter or the six-channel V730-1 VME O/E converter module.
Model J724-3 uses a 1310 nm Fabry-Perot laser with ST connector, intended for use with 9/125 micron singlemode fiber, but also usable with 62/125 micron multimode fiber. It can drive the J730-3 standalone O/E converter or the V730-3 VME six-channel receiver.
The Model J724-5 uses a 1550 nm Fabry-Perot laser with ST connector, intended for use with 9/125 micron singlemode fiber, but also usable with 62/125 micron multimode fiber. It can drive the J730-5 standalone O/E converter or the V730-5 VME six-channel receiver.
Because of the low temporal dispersion of singlemode fiber, a 1310 nm singlemode system will demonstrate superior timing stability and lower jitter over long distances.
Features
- Compact DC-coupled logic-level to fiberoptic converter.
- Available with 850 nm laser for multimode fiber, and 1310 nm or 1550 nm laser for single or multimode fiber.
- High noise immunity ensures error-free logic transmission in severe EMI environments.
- User-selectable input logic threshold and termination.
- Compatible with Highland model J730 standalone and V730 six-channel VME O/E converters
