Ericsson and Ciena collaborate on IP-over-WDM and SDN

Do company partnerships work? Ericsson and Ciena certainly think so, and provide a compelling argument for their collaboration in the areas of IP-over-WDM and software-defined networking (SDN). More such partnerships should also be expected.

Jan Häglund

Ericsson and Ciena have signed a global strategic agreement that provides Ericsson with Ciena's optical networking technology, while Ciena benefits from Ericsson's broader service provider relationships.

ClariPhy samples a 200 Gigabit coherent DSP-ASIC

ClariPhy Communications has entered the 100 Gigabit coherent merchant chip market after announcing first samples of its LightSpeed-II devices. 

The family of coherent digital signal processing ASICs (DSP-ASICs) is manufactured using a 28nm CMOS process. "We believe it is the first 28nm standard product, and leaps ahead of the current generation [DSP-ASIC] devices," says Paul Voois, co-founder and chief strategy officer at ClariPhy.

Xtera demonstrates 40 Terabit using Raman amplification

Feature: 100 Gig and Beyond. Part 2

• Xtera's Raman amplification boosts capacity and reach
• 40 Terabit optical transmission over 1,500km in Verizon trial
• 64 Terabit over 1,500km in 2015 using a Raman module operating over 100nm of spectrum  

Herve Fevrier

Optical transport equipment makers continue to research techniques to increase the data carried long distances over a fibre without sacrificing reach. The techniques include signal processing of the transmit signal to cram data-carrying channels closer in the C-band, advanced soft-decision forward error correction (SD-FEC) and receiver signal processing to counter transmission impairments.
