The implementation agreement specifies key aspects of integrated receivers for coherent DWDM applications. The IA supports DP-QPSK modulation as specified in the OIF's 100G Framework Document and also specifies operating rates up to 32GBd. The OIF said its implementation agreement strives to remain modulation format and data rate agnostic to maximize applicability to potential future applications. "Many vendors are currently developing coherent receivers based on the OIF's 100G receiver IA and their availability is already having a significant impact on the design of next generation of DWDM hardware," said Jeff Hutchins, CoreOptics and OIF Board member. In addition, the OIF has completed a Forward Error Correction (FEC) whitepaper summarizes its investigation of FEC for use with 100G DP-QPSK transmission in long distance DWDM communications. The paper examines the propagation challenges and suggests an upper bound for spectral coding overhead for the OIF's integrated photonics projects. The whitepaper complements and supports the work already underway defining 100G Ethernet in the IEEE and the OTU4 of the Optical Transport Hierarchy (OTH) in the ITU-T. http://www.oiforum.com/public/impagreements.html 10-May-10   Learn How to Get Your Video on this Site Recent Optical News China Telecom to Accelerate FTTH and Mobile Rollouts Colt Deploys Infinera in Low-Latency European Backbone AppliedMicro to Acquire TPACK for Emerging OTN Hong Kong's PCCW Deploys Huawei's 40G OTN Level 3 Wins Networx Contract for Social Security Administration EXFO Adds Tunable DPSK Testing to its 40G/43G Solution PMC-Sierra Collaborates with Incognito Software on FTTx for MSOs VI Systems Ships First Circular VCSEL Arrays EXFO Boosts its Optical Spectrum Analyzer Russia's FORATEC Selects Ciena's CN 4200 EU's BIANCHO Project Targets Energy Efficient Photonic Components CALIENT and Freeport Offer Govt Teleconferencing NSN Supplies LH DWDM for First Communications NTT Adds 588,000 Optical Access Lines in Q2 EXFO Boosts its Blazer Multiservice Test Modules > More news...
