Dual Wavelength Fiber Optic Laser Source And Detector Module - Order Code 28556

SPECIFICATION

Features

• Provision for Analog input, TTL input and RS-232 input
• Display to indicate forward voltage across and forward current flowing through LASER source
• Voltage and current is varies using intensity controle potentiometer
• Built in pulse generator with pulse widths of 30ns and 100ns
• All Connectors are suitable for ST type of connector interface

Laser Driver Circuit

• Digital and Continuous Wave Driver Circuits
• Two driver modes are available in this system, one for pulse operation and analog transmission, other for continuous wave operation and Digital Transmission
• These are controlled by rotary switch available on front panel.

Photodetector Circuit

• Photodetector produces current in response to optical input.
• This current produced is then converted to voltage and amplified by amplifier.
• This amplified output is measured as electrical output

Specifications

• Provision for analog input, TTL input and RS-232input
• Displays to indicate forward voltage across and forward current flowing through LED source
• Voltage and current is varied using intensity control potentiometer
