Introduction and Application of QSFP-100G-ER4 Optical Module

With the accelerated development of the Internet, cloud computing, big data and other industries, 100G products are used more and more widely, and the demand for long-distance products is also increasing. For long-distance transmission application scenarios, the traditional scheme requires DWDM equipment to increase the transmission distance. Its networking is complex, requires additional equipment costs, and has high maintenance costs. Using 100G-ER4 modules can simplify the transmission network, reduce relay equipment, and reduce maintenance costs. Next, we will introduce the optical modules that meet the QSFP-100G-ER4 standard.

QSFP-100G-ER4 optical module

QSFP-100G-ER4 module adopts hot pluggable QSFP28 package, single mode, central wavelength 1295, 1300, 1304, 1309, dual LC interface, operating temperature 0 ° C~70 ° C (commercial grade), maximum speed up to 111.8Gbps, and maximum transmission distance up to 40KM by matching with OS2 single mode jumper.

The QSFP-100G-ER4 optical module is widely used in the 100G Ethernet (100GBASE-ER4) of the data center. The QSFP-100G-ER4 optical module can be compatible with Huawei, ZTE, Dell, Cisco and other brand switches.

100G-ER4 optical module switch solution:

Take Huawei's CE8861 switch as an example. The CE8861 switch is mainly used in data centers and high-end parks. It has high-density 400GE/200GE/100GE/40GE/25GE/10GE ports and can be used with QSFP-100G-ER4 optical modules and OS2 jumpers to help enterprises and operators build a data center network platform for the cloud computing era.

The above are the common types of optical modules in the current 100G-ER4 standard. The QSFP-100G-ER4 optical module has the characteristics of high reception sensitivity, low power consumption, high reliability, etc. It can help users eliminate the relay optical amplification equipment, thus reducing the operating cost, and providing a low-cost solution for long-distance applications of 100GE ports between computer rooms.
