Finisar's 10 Gig bi-directional DWDM architecture

Finisar has developed a bi-directional 10-gigabit SFP+ module for the metro-access market. The dense wavelength-division multiplexing (DWDM) module is designed to expand capacity at locations where fibre is scarce. And being tunable, the SFP+ also simplifies network planning for the operators.

Finisar demonstrated the module working at the recent ECOC 2017 show held in Gothenburg.

 

Market applications

Interest is growing in using WDM optics for wireless, metro-access and cable networks that are undergoing upgrades. The interest in WDM at the network edge is due to a need to use fibre resources more efficiently. “We are seeing that globally, more and more dark fibre is being used up,” says Leo Lin, director of product line management at Finisar.

Leo LinGiven the cost of leasing and installing fibre, operators are keen to make the best use of their existing fibre and are willing to pay more for WDM optics.

According to Finisar, leasing a fibre can cost $250-$2,000 per fibre annually while the cost of installing fibre can be $500,000 per 10km. “Using WDM optics, you can get payback in less than a year,” says Lin.

LightCounting Market Research's latest forecast estimates that the global wireless transceiver market for 10 gigabit WDM will be approximately $400 million in 2022.

Finisar’s bi-directional 10-gigabit SFP+ product is also being aimed at two emerging ITU Telecom standards: G.metro and NG-PON2.

Books of the year 2016 - Part 2

More industry figures comment on books read this year. Here are Finisar's Simon Poole's and Ciena's Loudon Blair's recommendations.

Simon Poole, director, new business ventures, Finisar Australia

The highlight of the year in fiction was reading The Shepherds’ Crown, the last of the Discworld novels from the wonderful Terry Pratchett. He, along with his cast of extraordinary characters, including the marvellous Tiffany Aching – a fabulous role model for teenage girls, held up a mirror to the foibles and strengths of our humanity, and will be sorely missed.

OIF starts work on a terabit-plus CFP8-ACO module

The Optical Internetworking Forum (OIF) has started a new analogue coherent optics (ACO) specification based on the CFP8 pluggable module.

The CFP8 is the latest is a series of optical modules specified by the CFP Multi-Source Agreement and will support the emerging 400 Gigabit Ethernet standard.

 

Karl GassAn ACO module used for optical transport integrates the optics and driver electronics while the accompanying coherent DSP-ASIC residing on the line card.

Systems vendors can thus use their own DSP-ASIC, or a merchant one if they don’t have an in-house design, while choosing the coherent optics from various module makers. The optics and the DSP-ASIC communicate via a high-speed electrical connector on the line card.

ECOC '15 Reflections: Part 2 

Part 2: More industry executives share the trends and highlights they noted at the recent European Conference on Optical Communication (ECOC) event, held in Valencia. 

 

Martin Zirngibl, head of network enabling components and technologies at Bell Labs. 

Silicon Photonics is seeming to gain traction, but traditional component suppliers are still betting on indium phosphide.

There are many new start-ups in silicon photonics, most seem to be going after the 100 gigabit QSFP28 market. However, silicon photonics still needs a ubiquitous high-volume application for the foundry model to be sustainable.

There is a battle between 4x25 Gig CWDM and 100 Gig PAM-4 56 gigabaud, with most people believing that 400 Gig PAM-4 or discrete multi-tone with 100 Gig per lambda will win.

 

Will coherent make it into black and white applications - up to 80 km - or is there a role for a low-cost wavelength-division multiplexing (WDM) system with direct detection?

STMicro chooses PSM4 for first silicon photonics product 

STMicroelectronics has revealed that its first silicon photonics product will be the 100 Gigabit PSM4. The 500m-reach PSM4 multi-source agreement (MSA) is a single-mode design that uses four parallel fibres in each direction. The chip company expects the PSM4 optical engine to be in production during 2015. 

"We have prototypes and can show them running very well at 40 Gig [4x10 Gig]," says Flavio Benetti, group vice president, digital product group and general manager, networking products division at STMicroelectronics. "But it is expected to be proven at 4x25 Gig in the next few months." STMicroelectronics has just received its latest prototype chip that is now working at 4x25 Gig.

MultiPhy eyeing 400 Gig after completing funding round 

MultiPhy is developing a next-generation chip design to support 100 and 400 Gigabit direct-detection optical transmission. The start-up raised a new round of funding in 2013 but has neither disclosed the amount raised nor the backers except to say it includes venture capitalists and a 'strategic investor'.
