Analysis of business opportunities for new entrepreneurs of 100G optical module

With the development of broadband services, end users' requirements for service quality are constantly improving. Audio visual streaming services such as IPTV and OTT (OverTheTop) need greater bandwidth to ensure user experience; On the other hand, the large-scale application of cloud computing enables more services to be concentrated in the cloud machine room for processing, and a large number of storage and exchange processing needs, which makes the core router of the IDC upgrade to 10G or even higher speed, driving the backbone and urban network to develop towards greater bandwidth, so as to ensure that various services can be smoothly promoted.

In addition, the large bandwidth dedicated line business of enterprises has also grown rapidly, so the demand of telecom operators for 100G networks has increased rapidly. More telecom operators around the world have also successively invested in 100G construction in recent years, introducing a new generation of high-speed networks.

Since the IEEE 802.3ba standard was released in June 2010, the development of 40/100G has attracted much attention. At the American Optical Fiber Communication Exhibition (OFC) held in Los Angeles in March 2012, optical fiber chips, modules, system products and test manufacturers such as ZTE Communication and EXFO have successively introduced 40/100G technology related products. ZTE even proposed a test and experiment result report that 100G can be upgraded to 200G through its patented technology; IEEE has also begun to discuss the development of the 400G standard.

At present, 100G adopts dual polarization four phase shift keying (DP-QPSK) modulation standard with coherence detection technology, which has digital signal processing capability. 100G Linecard can provide remote real-time monitoring for optical transmission layer performance, and dispersion, delay and other conditions will be reduced. In addition, through software control, the transceiver can select specific wavelength channels for use. In the future, there may even be a software defined network (SDN) like mechanism to change the characteristics of network transmission.
