Fiber works were out of people’s imagination in the ancient times, but now numerous optical products have emerged rapidly and facilitate people’s life. In the meanwhile, 100G transceiver has become possible and springs up like the mushrooms. The following passage will give a lead to 100G transceiver.
100G transceiver provides customers 100 Gigabit Ethernet connectivity options for data center networking, enterprise core aggregation, and service provider transport applications. 100G transceivers offer significant advantages over existing solutions in terms of reduced power dissipation and increased density with the added benefit of pluggability for reduced first installed cost.

100G Transceiver

CFP and CXP are the two common types of 100G transceiver. The CFP defines hot-pluggable optical transceiver form factors to enable 40 Gbit/s and 100 Gbit/s applications. CFP modules use the 10-lane CAUI-10 electrical interface. While CXP modules use the CAUI-10 electrical interface, which is a multi-source agreement to produce a common form-factor for the transmission of high-speed digital signals. CXP optical transceiver is hot pluggable, and supports data rates of 40 Gbps. The CFP transceiver, as detailed in the MSA, supports both single-mode and multi-mode fiber and a variety of data rates, protocols, and link lengths, including all the physical media-dependent (PMD) interfaces, which is targeted at the clustering and high-speed computing markets.
As we all know, 100 transceiver has a very short history. On July 18, 2006, a call for interest for a High Speed Study Group (HSSG) to investigate new standards for high speed Ethernet was held at the IEEE 802.3 plenary meeting in San Diego. And in June 2008 Cisco Systems and Comcast announced their 100GbE trials. In October 2008, Huawei presented their first 100GbE interface for their NE5000e router. And On February 16, 2015, the IEEE 802.3bm standard was approved. Since then, 100 transceiver achieves mass production and sales of 10G, 40G, and 100G transceivers for enterprise and data center applications grew rapidly in 2014.From the table below, We know that the market for 100G data center optics is accelerating, but it has yet to be turbocharged by widespread data center deployment in the way 40G transceiver has. And the popularity of 40G transceivers accounted for much of the upswing. Overall, the long-anticipated ramp of 100G transceivermay be at hand and the ongoing movement to 100G and price declines will put revenue pressure on both 10G and 40G. Major growth in the data center for 100 Gigabit Ethernet is on the horizon due to more service providers applying 100G transceiver equipment in their core networks and new silicon entering the market.

Customers often feel puzzled about how to select between single mode fiber and multi mode fiber due to its similar function. While in 1980, Professor Huang Hongjia of the Chinese Academy of Sciences recognized that single mode fiber, compared to multi-mode fiber, has the characteristics of lower loss, narrower modal dispersion and have a higher bandwidth, which is ideal for medium capacity long-range communication system. At the same time he developed coupling wave theory in the field of microwave theory and successfully developed single mode optical fiber.
