Application of Burst Bit Error Meter in OLT module
In the PON system, the OLT is connected with multiple onus (optical network units) through POS (passive optical splitter). As the core of PON, OLT optical module will directly affect the operation of the whole PON system.
Nexustest PAM4 oscilloscope helps optical communication
The R & D and production of optical communication networks and high-speed interface optical chips, optical devices and optical transceiver modules require high-performance sampling oscilloscopes for accurate measurement and verification.
Application of fast wavelength meter in tunable laser calibration
A very important test of tunable lasers is accurate wavelength measurement and calibration. With the continuous increase of communication channels, from the first 40 waves to the current maximum of 80
