Fujitsu Intros 40 Gbps Coherent Optics

Fujitsu has announced the addition of third generation 40 Gbps optical interfaces to its FLASHWAVE 7500 Reconfigurable Optical Add/Drop Multiplexer (ROADM) platform.


Coherent receivers offer many advantages, including improved optical performance, which allows for larger geographic networks with longer optical spans. Utilizing all-electronic compensation, coherent optics eliminate the need for dispersion compensation modules and improve operational flexibility.


“The market for 40G transport gear surpassed $500 million in 2009 as carriers around the globe embraced the technology,” said Ron Kline, principal analyst of network infrastructure at Ovum, in a statement. “The latest Fujitsu 40G products respond to evolving and growing market needs for systems with higher tolerance to dispersion while at the same time shortening the 100G developmental cycle. We expect the market for 40G to double this year and exceed $3 billion by 2014.”


The new 40 Gbps coherent interfaces for the FLASHWAVE 7500 ROADM include individual transponder, muxponder, and regenerator units. Combining advanced coherent detection technology with dual polarization quadrature phase shift keying (DP-QPSK) modulation, these new units enable enhanced performance on ultra-high speed 40 Gbps wavelength division multiplexing (WDM) networks.
