Server access and switches interconnection requires faster speed to meet increasing demand for bandwidth of streaming video, cloud computing and storage and application virtualization, optical transceiver not only plays an important role in modern data centers, and it is also importance in the next few years. What challenges will the data center application bring to the optical module? How does the fiber optic transceiver itself evolve to fit the data center in the future? The first challenge is the cost of optical transceiver.

There are thousands of devices running in big data centers. Suppose that in a data center there are one hundred thousand server devices that are connected to each other by highly redundant mesh networks, in other words, the number of optical links required to implement this huge connection is also one hundred thousand. Because both ends of each optical link needs optical transceiver. So, the number of optical modules is at least two times the number of optical links. In fact, if you use optical packet allocation, the number of fiber optic transceiver may be even more. There is no doubt that such a large number of optical module requirements will cost a lot, and the high cost is not conducive to the development of data centers. Therefore, it is imperative to develop low cost optical transceivers. How to reduce the cost of optical transceiver has become a big challenge for optical module suppliers.

To be honest, it is very difficult to reduce the cost if only minor improvements are made in the design and manufacturing methods of the optical transceiver. Since there is little effect in this respect, we can only relax the standard to achieve the purpose of reducing costs. For example, by reducing the maximum operating temperature, reducing operating temperature range, shortening the service life of the fiber optic transceiver and allowing the use of forward error correction technology to reduce costs. These measures allow suppliers to take a high level of optical integration to achieve low cost optical transceiver design, non hermetic package, non cooling operation and simplified testing.

Now the optical transceiver market is quite mature. Thanks to MSA Agreement (Multi-Source), end users have more choices when choosing suppliers, and they don't have to spend money to buy expensive products directly from system vendors.
