With the rapid advancement of 5G networks, optical communication technology has ushered in unprecedented changes. Dense wavelength division multiplexing (DWDM) systems have become the core of modern fiber optic communication networks due to their efficient data transmission capability and spectrum utilization. However, the dense channel distribution and high-speed data transmission in DWDM systems place higher requirements on the optical spectrum analyzer (OSA).

On the basis of mature DWDM, EDFA and other technologies, ultra-high-speed optical communications require a fuller use of the optical spectrum bandwidth and carrier information, based on the existing fiber optic networks, equipment, technology provided by the transmission channel to multiply the expansion of data traffic.

Capable of measuring in the visible to near-infrared wavelength bands from 350 nm to 1200 nm, the 6362C Spectrum Analyzer meets the growing demand for medical, biological and materials processing applications. 6362C Spectrum Analyzer offers high wavelength resolution and a wide dynamic range for clear characterization of spectral details and fine reproduction of spectral signatures.

The BERTWave MP2110A all-in-one instrument is used in multi-channel module evaluation, TOSA/ROSA evaluation, and active optical cable (AOC) and direct-attached cable (DAC) evaluation. The instrument is capable of performing Tx/Rx signal wavemask margin testing, Rx signal eye diagram analysis (including jitter, Tr/Tf, etc.), Tx signal eye diagram analysis (including jitter, Tr/Tf, extinction ratio, etc.), and Rx signal receive sensitivity testing (BER measurement).
