The 100G era has arrived, and the demand for 100G optical modules has increased significantly

Due to the rapid growth of global network traffic promoted by 4K HD video, live broadcast, VR and other new applications, and the higher requirements of cloud computing, laaS service, big data and other emerging applications on data center data transmission, the global data center has been upgraded from 10G/40G to 25G/100G. As a result, the demand for 25G/100G optical modules increases. This article will tell you how big the market demand for 100G optical modules and what types of 100G optical modules are.

According to the world famous institutions, in 2018, the global 100G optical module market scale reached about 3 billion dollars. It is expected that in 2019, with the explosion of demand for 100G optical modules in medium and large data centers such as Facebook, Amazon, Aliyun, Tencent, Huawei, the global shipment is expected to continue to double. The market size will be about $3.6 billion.

In the future, 100 g light module of life cycle is very long, even though there are 200 g, 400 g or 800 g optical module, considering factors such as cost, and reliability, will not appear on a large scale commercial, the 100 g is different, in addition to the large scale of data center applications, small data center convergence layer to the core switch will be used, Therefore, the 100 Gbit/s optical module is widely applicable. The following is an inventory of the types of 100G QSFP28 optical modules.

1. 100G QSFP28 multi-mode optical module

The 100G QSFP28 multimode optical module is usually connected with OM3 and OM4 multimode fiber jumpers for transmission. OM5 can also be used as required. The optical module in the following table uses OM4 optical fibers for transmission distances.

2. 100G QSFP28 single-mode optical module

The 100G QSFP28 single-mode optical module adopts four channels of 25G 1310 wavelength, single wave of 100G 1310 wavelength, four channels of 25G CWDM coarse wavelength division multiplexing and four channels of 25G LWDM fine wavelength division multiplexing to transmit the 100G link.
