With the rapid development of Internet, cloud computing and big data industries, the application of 100G products is more and more widely, and the demand for long-distance products is also increasing. For the long-distance transmission application scenario, the traditional scheme needs to use DWDM equipment to increase the transmission distance. Its networking is complex, needs additional equipment costs, and the maintenance cost is high. Using 100G-ER4 module can simplify the transmission network, reduce the relay equipment and reduce the maintenance cost. Next, ETU-Link will introduce the optical modules that meet the QSFP-100G-ER4 standard.

QSFP-100G-ER4 optical module

QSFP-100G-ER4 module adopts hot-swappable QSFP28 package, single-mode, central wavelength of 1295, 1300, 1304, 1309, dual LC interface, working temperature of 0 ° C-70 ° C (commercial grade), maximum speed of 111.8gbps, and the maximum transmission distance can reach 40km by matching with OS2 single-mode patch cord.

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

100G-ER4 optical module-Switch solutions:

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

The above are the types of optical modules commonly used in the current 100G-ER4 standard. The QSFP-100G-ER4 optical module of easy sky optical communication has the characteristics of high receiving sensitivity, low power consumption and high reliability, which can help users avoid the relay optical amplification equipment, thus reducing the operation cost, and providing a low-cost solution for the long-distance application of 100GE ports between computer rooms.
