Model 2502 photodiode meter is specially designed for the production test of laser diode module, which greatly increases the production capacity of the Kishli Liv (optical-current-voltage) test system. Developed in close collaboration with leading LDM manufacturers for optical fiber communications networks, the dual-channel instrument features easy synchronization with other system components. The close control of optical power measurement .2502 has a high-speed analog output port, which supports the use of LIV test system in the optical fiber calibration phase of the LDM manufacturing process. By using the buffer memory and the Trigger Link interface specific to the Hirschley instrument, the Trigger Link 2502 can provide users with the maximum capacity of the current laser diode module LIV test. The design of these instruments greatly meets the requirements of reliability and repeatability for continuous operation in 24 hours production environment.
