100G QSFP28 BIDI 20km optical transceiver launched by Fiber Mall

With the rapid development of optical networks, fiber resources will become increasingly scarce, and the demand for solutions to save fiber resources will gradually increase. At the same time, it is also a trend that the normal operation of optical transceivers is not affected by changes in ambient temperature, so it does not need to be deployed in the equipment room, therefore,the requirements for site selection are greatly reduced, and subsequent maintenance costs are saved.

Based on this, Fiber Mall has created a QSFP28 packaged product that not only adapts to the outdoor temperature but also saves fiber resources — 100G QSFP28 BIDI optical transceiver. Compared with the conventional 100G QSFP28 optical transceiver, this product solution saves 50% of optical fiber resources and can be widely used in the fields of telecommunications, data centers and wireless communications.

The product solution launched by Fiber Mall uses different transmitting and receiving wavelengths, and realizes single-fiber bidirectional transmission through WDM multiplexing, which solves the reflection problem during the operation of the circulator solution, and greatly reduces the difficulty in engineering use and maintenance for customers. Although this solution increases the difficulty in design, it greatly improves the overall stability and reliability of the product in use, and highlights Fiber Mall’s design concept: provide customers with high-quality products and put customers first at the design stage.

This product uses a 100G BIDI optical device developed with a self-made 25G optical chip, which achieves a working temperature range of -20~85 °C, a maximum power consumption of 5W, and can achieve 20km transmission. It fully complies with the 100G BASE-LR4 standard and 100G 4WDM-20 MSA standard in IEEE802.3ba international standard.

Fiber Mall’s mission: to provide global customers with optical communication solutions and cost-effective products! We continue to focus on the pain points of customers, and will continue to launch differentiated products to create value for customers.
