consumption. Furthermore, increased capacity through higher spectral efficiency has always been the driver of long haul economics, and TeraWave fiber supports this increase through optimized fiber properties. “Thisachievementwill have increasingvalue as transmission technology approaches the ‘non-linear Shannon limit’. TeraWave fiber increases the practical capacity of optical fiber to better support future bandwidth demands.” TE Connectivity (TE) has revealed its latest development in fiber optics, its Coolbit optical engines. This platform engine, which converts data from electrical signals to optical signals, will be thedriving technology behind TE's 100G, 300G and 400G active optics. During 2014, TE will bring four active optics products to market that will include Coolbit optical engine platform: 100G QSFP28 active optical cables (AOCs); 100G QSFP28 transceivers; 300G mid-board optical modules; and 400G CDFP AOCs. TE’s latest 25G active optics are designed to help to achieve the cooling at component level that is so important as data center energy consumption concerns rise, along with the need for more data. Power consumption is low, with QSFP28 modules performing at less than 1.5 watts per transceiver. At component level alone, Active optics platform technology

AllWave One fiber provides reliable performance, superior to ITU-T G.652.D and G.657.A1 recommendations. With a composition of high purity synthetic silica throughout the core and cladding, the fiber offers mechanical reliability and stable low loss. OFS's patented ZWP fiber manufacturing process eliminates hydrogen-aging defects and provides a 50 percent increase in usable spectrum compared to G.652.A and G.652.B fiber. OFS’ TeraWave™ fiber is an improved ITU-T G.654B large area single-mode fiber designed for 100GB/s and 400GB/s coherent transport in terrestrial long haul systems. TeraWave fiber has been designed to provide higher transmission speeds over longer distances with more wavelengths, reducing the need for signal regeneration. TeraWave fiber offers a combination of optimized effective area, high cabling performance, and reduced attenuation compared to conventional ITU-T G.652.D single-mode fibers. With 50 percent of the effective area of conventional G.652.D fiber types, TeraWave reduces nonlinear impairments for coherent transmission, enabling the launch of higher signal power for increased optical signal noise ratio (OSNR). David DiGiovanni, chief technology officer of OFS, said: “The longer optical reach enabled by TeraWave fiber means fewer regeneration sites helping to save capital cost, rack space in huts, and power Long haul fiber
