100G Ethernet Develops Rapidly With the increasing demands of higher speed and greater bandwidth, more and more people are looking forward to the coming of 100G Ethernet. In fact, with the rapid development in these few years, 100G Ethernet is getting closer to us. According to the latest report from Infonetics, 100G accounts for over half of all bandwidth deployed in carrier networks in 2014, and will grow rapidly through 2018. As you can see from the diagram below, in 2014, the 100G is on par with the 10G, but in 2016, it exceeds the 10G and grow rapidly in 2018.The explosive growth in mobile data traffic, data centers, and cloud services are the catalysts behind significant traction of 100G deployments in the Core and Long Haul networks. Service providers and carriers are accelerating the deployment of 100G but also looking carefully to manage their CAPEX and OPEX effectively. Many company, such as Cisco, Alcatel-Lucent, Brocade, and Juniper Networks have introduced 100G equipm..
The C form-factor pluggable (CFP) is a multi-source agreement to produce a common form-factor for the transmission of high-speed digital signals. The c stands for the Latin letter C used to express the number 100 (centum), since the standard was primarily developed for 100 Gigabit Ethernet systems.The CFP transceiver is specified by a multi-source agreement (MSA) between competing manufacturers. The CFP transceiver was designed after the small form-factor pluggable transceiver (SFP) interface, but is significantly larger to support 100 Gbit/s. While the electrical connection of a CFP transceiver uses 10 x 10 Gbit/s lanes in each direction (RX, TX) the optical connection can support both 10 x 10 Gbit/s and 4 x 25 Gbit/s variants of 100 Gbit/s interconnects (typically referred to as 100GBASE-SR10 in 100 meter MMF, 100GBASE-LR10 and 100GBASE-LR4 in 10 km SMF reach, and 100GBASE-ER10 and 100GBASE-ER4 in 40 km SMF reach respectively.)CFP transceivers can support a single 100 Gbit/s signal l..

With the rapid development of optical communication in recent years, users have increasing demands for the network. In this condition, 100G optical module has become the hot focus that users care. What is a 100G optical module? This post will give a complete introduction and guide about 100G optical modules.1. Introduction of 100G optical modules100G optical module was created to adapt to the trend that network market is developing to 40G and 100G, with a transmission rate of 100G, this module plays a significant role in 100G network system deployment.2. Technology development of 100G optical modulesCompared with the 2.5G, 10G or 40G wavelength division transmission systems, the 100G optical transmission uses the digital coherent receiver to map all the optical attributes of the optical signal to the electric domain through the phase diversity and the polarization state diversity. Using the mature digital signal processing technology achieve in the electric domain polarization demultip..
