Optical communications technology provider, Opnext has revealed the 100Gbps Dense Wavelength Division Multiplexing MSA transponder module, the OTM-100. The release was announced 18 months after the company demonstrated the technology to European and North American networks.
The OTM-100 is available in an industry standard module of 5-inch X 7-inch and offers cost, performance and size benefits as the module is based on the second generation coherent technology.
A fully integrated optical transponder, the OTM-100 allows network equipment dealers to develop 100Gbps regional, submarine, long haul, metro and ultra long haul transport solutions. The digital signal processor developed by NTT Electronics features a Digital Coherent Signal Processing LSI, a result of a project supported by Japan’s Ministry of Internal Affairs and Communications, titled R&D on High Speed Optical Transport System Technologies. By applying Soft-Decision Forward Error Correction, extended reach of the optical module is achieved, thus reducing operating costs since the requirement of regeneration costs can be reduced along with the simplification of network deployment rules.
The Opnext OTM-100 module is best suited for transport systems with integrated inline dispersion compensation modules as well as certain advanced systems. Coherent detection technology allows for tolerance of impairments such as Polarization Mode Dispersion and Chromatic Dispersion. With reduced channel impairments, the OTM-100 can be used in functional fiber optic plants designed for 2.5Gbps and 10Gbps.
Carriers will be able to upgrade their line systems to 100Gbps with Opnext’s plug-n-play technology. The optical technology can be deployed over fibers with meager transmission characteristics as well as reduce IP latency and reduce cost by eliminating external dispersion compensation.
