This optical module supports hot-swappable functionality, which greatly simplifies the installation and maintenance process, saving a lot of time and energy for network managers. Its maximum data transmission rate can reach 112Gbps (4x28Gbps), which can easily meet the needs of fast transmission of large-capacity data. Whether it is internal data interaction of large enterprises or information transmission between data centers, it can handle it with ease.


In terms of transmission distance, it performs exceptionally well, supporting a maximum transmission distance of 30km. When used with single-mode fiber (SMF) and with the 1310nm wavelength, it can effectively reduce signal attenuation and ensure the stability and integrity of data during long-distance transmission. The connector adopts the LC type, and only 2 fibers are needed to realize data transmission, which not only guarantees performance but also reduces wiring costs and complexity.

At the same time, its maximum power consumption is only 5.0W, achieving energy saving and consumption reduction while ensuring efficient transmission. It adopts a LAN WDM EML laser and an APD receiver, further improving the quality of signal sending and receiving. The QSFP28 MSA package with a duplex LC connector has a compact and reasonable design, facilitating installation and integration. In addition, it is equipped with a two-wire serial interface and digital diagnostic monitoring functions, which is convenient for real-time monitoring of the module's operating status and timely detection and resolution of problems. Moreover, the product uses a single 3.3V power supply voltage, complies with the RoHS standard, is environmentally friendly and stable, and has an operating temperature range of 0℃ to 70℃, which can adapt to different environmental conditions.

In terms of application scenarios, the 100G QSFP28 ER4 30KM EML 1310nm LC SMF also performs brilliantly. It can be widely used in fields such as 100GBASE-ER4 100G Ethernet and ITU-T OTU4, providing reliable hardware support for high-speed Ethernet transmission and telecom-level optical transmission.


In terms of performance parameters and application range, the 100G QSFP28 ER4 30KM EML 1310nm LC SMF is a highly competitive optical module product, which can provide stable and efficient solutions for various network transmission needs.
