Yesterday, China Telecom Zhejiang company started 2015 optical modules centralized procurement tender, the tender for the procurement content Zhejiang branch of China Telecom Corporation Limited and its subsidiaries in 2015, 2016 MAN engineering and other related projects supporting the optical module products, estimated size of about 120,000 purchase.

Optical module vendors Menara network has said its direct detection tunable DWDM 100G CFP optical module has achieved volume sales. Menara also introduced its 100G Wave Master wavelength adjusting and BER tester.

According to Infonetics latest report on 10G / 40G / 100G optical modules noted that the enterprise network and data center applications 10G / 40G / 100G optical module market in 2014 grew by 21% to reach $ 1.4 billion, the second half of 2014 with the entire data center 40Gbps module market grew by 81% a year ago. The company also forecast that demand for data center 100G modules for the start, in 2016 there will be a substantial increase.

Innovative provider of world-class design and production company OFS fiber optic network equipment and solutions, recently expanded the overland distance applications, the introduction of ultra-low-loss optical fiber TeraWave ™ ULL than G.652.D 50% larger effective area fiber and 1550nm attenuation of less than 0.17dB/km. For the growth of T-bit transmission market, OFS's TeraWave ULL optical fiber is ultra-low-loss version designed to improve system performance TeraWave coherent long-distance optical fiber. TeraWave fiber has a longer transmission distance and accommodate more wavelengths than the ITU-T G.652.D fiber, reducing the need for expensive signal relay.

Germany ADVA optical transmission equipment manufacturers, recently said that the successful completion of 400Gbps optical transmission experiment a data center interconnect environment. Poland Poznan Supercomputing and Network Center PSNC with ADVA use PIONIER's research and education network from Warsaw to Poznan fiber network carried out the experiments. Experimental network also includes hybrid ROADM and amplifier.

Recently, Gigalight launched the second generation of the optical module tester 10G SFP+ Checker, integrated support up to 10G bit error rate testing, optical power test, read and write EEPROM, DDM monitor a variety of functions in one, with high precision, low power consumption, lightweight and easy to carry and so on. Suitable for flexible deployment scenarios site identification and checking work status and performance SFP+, which greatly helps integrators, engineering users streamline operations and reduce operating costs.

CommScope has introduced broad-based with its SYSTIMAX LazrSPEED 550 multimode fiber WBMMF cable products. This fiber can support four wavelengths 850nm to 950nm transmitted simultaneously, rather than that single wavelength ordinary OM4 fiber. CommScope OFC once during the year, and Finisar exhibited together with the application of short-wavelength WDM optical modules and this fiber. The use of this fiber provides a new option for reducing costs from 40G to 400G optical modules of various types. In addition, this fiber also supports traditional OM4 fiber applications.

Principle of optical fiber communication is first necessary to transfer in the sender information (such as voice) into electrical signals, and then modulated onto the laser beam emitted from the laser, so that the intensity of light with the electric signal amplitude (frequency) changes, and sent through an optical fiber; at the receiving end, the detector receives the optical signal converts it into an electric signal, after demodulation to restore the original information.

All-optical switching is the future direction of development, but also from the current development trend, this "future" is not far away. Many in the industry view: ROADM-based networking and scheduling is not sensitive to the rate applicable to ultra-high-speed optical networking and scheduling transmission systems, but also can greatly reduce power consumption and floor room. After years of gradual improvement technology, functionality and performance, CDC-F ROADM (ie colorless and directionless without conflict and supports flexible grid capacity reconfigurable optical forked Multiplexer) device has matured, basically solved the light layer networking encountered many problems. Some foreign operators in the deployment of 100G networks have begun to do large particles using ROADM traffic scheduling, a direct transition to an all-optical network. March 2015, Verizon announced the adoption of Ciena and Cisco's packet optical transport platform Metro 100G deployment, CDC-F ROADM technology for the first time to get a commercial scale. In the same month, Alcatel-Lucent announced that Verizon will use its latest CDC-F ROADM technology to upgrade Verizon's long-haul optical transport network.
