Over the past 100 years, mankind has evolved from simple telegraph communication to today's 5G communication, and life has changed dramatically with increasingly widespread applications such as live streaming, VR / AR, ultra-HD video conferencing, telemedicine, autonomous driving and smart homes. And all of these need to be based on high-speed data transmission.

It is reported that the 2022 common fiber optic cable products centralized procurement project procurement scale of about 31.03 million skin length kilometers (equivalent to 846.7 million core kilometers), specifications for GYTA / GYTS / GYTA53, etc., the project funding source for self-financing 7.11 billion yuan, the bidders for China Radio and Television Network Corporation, the bidding content for ordinary fiber optic cable and cable processing Part.

In 2015, the competitive landscape of the optical module market was highly fragmented, with less than 20% of the market share held by the leaders and single-digit market shares held by the remaining vendors. However, with the development of technology, research and development and expansion threshold continues to improve, the scale advantage of large leading manufacturers is becoming more and more significant. In addition, in recent years, optical module companies have accelerated mergers and acquisitions, vertical integration of the industry chain, and further increase the concentration of the industry, the global optical module market will gradually move toward concentration.

Higher technical barriers and complex processes, optical chip in the optical module cost accounted for a relatively high. The main body of TOSA is the laser chip (VCSEL, DFB, EML, etc.), and the main body of ROSA is the detector chip (APD/PIN, etc.). (APD/PIN, etc.).

Optical Module (Optical Module) consists of optoelectronic devices, functional circuits and optical interfaces, etc. The optoelectronic devices include two parts: transmitting and receiving. The role of the optical module is photoelectric conversion, the transmitter side of the electrical signal into optical signals, through the fiber optic transmission, the receiver side and then convert the optical signal into electrical signals.

The MS9740B spectral analyzer achieves an overall test speed of less than 0.2 seconds from waveform scanning to waveform resolution and data transfer to external control devices, and with enhanced VBW settings (1 kHz and 200 Hz) commonly used by users, the MS9740B not only maintains the same measurement sensitivity as previous models, but also reduces measurement time by 50%, helping to further improve user productivity.

The N7745C is a replacement for the Yeste N7745A optical power meter, which is deeply optimized for high measurement throughput and can be used to characterize multi-port optical devices such as multiplexers, PON splitters, wavelength selective switches (WSS) and ROADMs. The instrument features high-speed measurement data acquisition capabilities and a faster data interface, and uses dual-port RAM to allow simultaneous measurement and reading of results without interrupting either operation.

The MP2100B Anritsu BERTWave is an all-in-one tester with built-in BERT and sampling oscilloscope for supporting optical module evaluation, including BER measurement, eye diagram template testing and eye diagram analysis.
