Technical analysis of optical transceiver: how to influence server technology 2015.05.23
 Every day, data centers need to deal with the massive data, and need to record the speed of data retrieval.This requires that every aspect of the design need to be well optimized, including the use of fiber optic transceiver technology. Since most of the data centers now have 100Mbps or higher network connectivity, all fiber-optic transceiver technologies, including 10Gbps, must meet the growing demand for bandwidth. The technology needs to meet the bandwidth requirements not only for the storage and application of the handover, but also for server applications. In this paper, we will introduce some of the information about the fiber optic transceiver and server technology you need to understand..

Fiber optic transceiver: smaller, cheaper, more energy saving

High port density in 2003 be in fashion in one's time. Since then, designers have begun to need the fiber optic transceiver, which not only consumes less energy, but also has lower cost and smaller scale.. The industry is generally considered that fiber optic transceivers meet the designers of these requirements and are in the technology field to be popularized and promoted through XFP multi-source protocol (MSA).

Fiber optic transceiver package is shrinking. The evolution from the size of a package of 4 "* 3.5" to 2.3 "x 0.68" packaging. This is a major change, so that the total server area to reduce, but also makes the size of the data center becomes smaller, more streamlined.

In addition, optical fiber transceiver power consumption is greatly reduced, from 10 kilowatts dropped to 3 watts or less, this is undoubtedly technology and a major leap, so that designers can obtain more transceiver technology. Lower power consumption means lower design prices and power costs. These savings are incredible for people in the technical field.

Advances in silicon technology have made all these advantages possible.. Supply manufacturers introduced fiber optic components, and promote the development of new transceivers. This aspect of evolution and development can help enterprise customers achieve 10Gbps, and enable them to migrate from 10 Mbps to 100 Mbps network, while the cost price continues to fall. This is why it is said that designers must keep pace with the times and solve the old problems by constantly seeking new solutions..

In the transceiver design, port density is one of the most important factors. Most data centers are composed of multi - exchange equipment frame, which can achieve high-speed processing. In order to control costs, data center designers improved their design, and try to improve their production technology, so as to further the realization of control cost of this effort. And increasing the port density is one way to reduce the cost of the system..

The XFP fiber transceiver supports up to 16 channels, which can be inserted into a standard server machine rack. Although the high port density is necessary for reducing the cost, it has become a key problem to solve the heat dissipation problem.. Electricity demand can be satisfied by using VCSEL technology, and it is also through the use of the latest silicon technology. XFP 10 Gbps fiber transceiver in the acceleration of the greatly improved, but also made considerable efforts in the fusion.

The XFP optical transceiver has been designed to meet the server requirements, and can meet the performance and distance requirements of 10 Gbps Ethernet. A XFP fiber optic transceiver can easily meet the server transmission rate and coding conditions. With the development of network technology, related technology of optical transceiver will follow. When the designer moved the digital function from the transceiver to the ASIC (dedicated IC), the efficiency of the transceiver was improved.

Low efficiency of XFP transceiver

The problem of overcoming the loss associated with the optical transceiver is the main concern of the XFP transceiver.. Crosstalk between telecommunication channel is another issue of concern. As the technology improves and the efficiency is reduced to a minimum, the server will become more efficient. This aspect of the work needs the designer and the manufacturer to provide some assistance, the aid content is mainly the server and the transceiver technology development.

Remember, the optical transceiver on a server converts electrical signals into optical signals. This allows them to achieve faster than 25 Gbps. However, if their volume is too numerous, they are more likely to cause transmission loss and signal attenuation, and this is undoubtedly another obstacle to faster transmission.

In order to solve these problems, the corresponding circuit technology has been appeared in the XFP transceiver to restrain the reflection and improve the data transmission rate.. At the same time, the effort is also carried out in order to reduce the cost and the floor area of the printed circuit board and the optical device.. Some companies have developed thin film lenses to solve these problems, but they did not completely eliminate them. And the future of technology or will eliminate the existence of this barrier.
