Analysis of the Advantages of 100G QSFP28 LR4 Optical Module

Rapid growth in digital information demands increasingly urgent requirements for high-speed, high-capacity networks, where the speed and distance of data transmission become key challenges. In this context, the 100G QSFP28 LR4 optical module, as an outstanding performer, offers a novel solution for long-distance high-speed transmission.

This product is designed specifically for 100G BASE-LR4 optical communication applications, providing 100Gb/s transceiver modules. The module converts 4 channels of 25Gb/s electrical data input into 4 LAN WDM optical signals, which are then multiplexed into a single lane for 100Gb/s optical transmission. Conversely, at the receiving end, the module demultiplexes the 100Gb/s optical input into 4 LAN WDM optical signal channels, which are then converted into 4 electrical signal output channels.

The 100G QSFP28 LR4 optical module is designed according to the Multi-Source Agreement (MSA) for QSFP form factor, supporting DDM digital diagnostic functions. Its design meets the most demanding external operating conditions including temperature, humidity, and electromagnetic interference.

The center wavelengths of the 4 LAN WDM channels are 1295.56nm, 1300.05nm, 1304.58nm, and 1309.14nm, serving as members of the LAN WDM wavelength grid defined in IEEE 802.3ba. The product features high-performance cooled LAN WDM EA-DFB transmitters and high-sensitivity PLN receivers, providing excellent performance for 100G Ethernet applications, using LC interfaces, with a maximum transmission distance of up to 10km.

With the development and application of cloud computing, big data, and artificial intelligence, the processing capabilities of data centers face significant challenges. The high-speed and long-distance transmission characteristics of the 100G QSFP28 LR4 optical module make it an ideal choice for high-speed data transmission within and between data centers.

The 100G QSFP28 LR4 optical module is highly suitable for long-distance connections in data centers and enterprise networks, such as 100G direct connections and interconnections. The direct connection scheme for 100G is straightforward, requiring only two QSFP28 LR4 optical modules to be inserted into corresponding 100G switch ports, connected by an LC fiber optic patch cord.

To address the transmission of large amounts of data, the application of the 100G QSFP28 LR4 optical module in the construction of metropolitan and wide area networks significantly increases the transmission speed while meeting the demand for long-distance transmission.
