LTX-721X Analog/Digital Fiber Optic Link

The LTX-721X Bidirectional Fiber Optic Links multiplex one analog signal along with up to 4 independent TTL/CMOS/LVTTL digital channels to over 10 kilometers with a single fi ber. The incoming analog data is digitized to 12 bit precision at up to 100 mega samples per second and the digital channels operate at data rates of 0 to 50Mb/s. This is then transmitted at speeds up to 2 Gb/s second for distances up to 10 kilometers. The digital signal is then received and the analog signal is accurately reproduced at the far end of the fi ber optic link.

Depending on the model the analog signal bandwidth may be from DC to 25 MHz (-3dB). The LTX- 721X has input voltage ranges of ±1 Volt or ±5 Volts. The input impedance of the analog channel may be set to 50 ohms or 1 megohm (75 ohms is optional).

The LTX721X series has a battery option that will allow for up to 4 hours of operation for experiments at extremely high potentials.
