Friday, October 15, 2010 at 10:06AM In the second and final part, Rafik Ward, vice president of marketing at Finisar, discusses Google’s call for a new 100 Gig interface, the ECOC show, and what Finisar has learnt from running a corporate blog.
"Feedback we are getting from customers is that the current 100 Gig LR4 modules are too expensive"

Thursday, October 14, 2010 at 7:45AM Briefing: Data centre switching
Part 1: Single-layer switch architectures
Juniper Networks’ Stratus switch architecture, designed for next-generation data centres, is several months away from trials. First detailed in 2009, Stratus is being engineered as a single-layer switch with an architecture that will scale to support tens of thousands of 10 Gigabit-per-second (Gbps) ports.
Stratus will be in customer trials in early 2011.

"This is probably the strongest growth we have seen since the last bubble of 1999-2000." Rafik Ward, Finisar
Thursday, September 23, 2010 at 6:49PM Google caused a stir at ECOC by requesting a new 100 gigabit-per-second (Gbps) interface, claiming the existing 100 Gigabit standards fall short of what is needed.
According to a report by Pauline Rigby, Google wants something in between two existing IEEE interface standards. The 100GBase-SR10, which has 10 parallel channels and a 125m span, has too short a reach for Google.
“What is good for an 800-pound gorilla is not necessarily good for the industry. It [Google] should have been at the table when the IEEE was working on the standard."

Tuesday, September 21, 2010 at 5:02AM Cisco Systems’ acquisition of CoreOptics means the company has largely cornered the coherent market, says Telecom Pragmatics.
Cisco Systems announced its intent to acquire the optical transmission specialist CoreOptics back in May. CoreOptics has digital signal processing expertise used to enhance high-speed long-haul dense wavelength division multiplexing (DWDM) optical transmission. Cisco’s acquisition values the German company at US $99m.
"Let me be clear, we don’t believe 100Gbps serial will dominate the market for a long time, or 40Gbps for that matter"

The table shows the selected players in AT&T's domain supplier programme announced to date.
AT&T has stated that there will likely be eight domain supplier categories overall so four more have still to be detailed.
Looking at the list, several thoughts arise:
Tuesday, September 7, 2010 at 6:48AM Significant power, size and cost challenges must be overcome before WDM-PON will be widely deployed.
"We see just one way to bring down the cost, form-factor and energy consumption of the OLT’s multiple transceivers: high integration of transceiver arrays"
Klaus Grobe, ADVA Optical Networking
Considerable engineering effort will be needed to make next-generation optical access schemes using multiple wavelengths competitive with existing passive optical networks (PONs).
Such a multi-wavelength access scheme, known as a wavelength division multiplexing-passive optical network (WDM-PON), will need to embrace new architectures based on laser arrays and reflective optics, and use advanced photonic integration to meet the required size, power consumption and cost targets.
