Cisco Systems' coherent power move

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 InfiniBand roadmap gets redrawn

The InfiniBand Trade Association (IBTA) has announced a new roadmap for the low latency bi-directional link. What was Eight Data Rate InfiniBand will now be known as Enhanced Data Rate (EDR) and be upgraded from 20Gbps to 26Gbps per channel. EDR will deliver a 104Gbps data rate in a four-channel InfiniBand (4x) implementation and 312Gbps when used as a 12-channel (12x) interface.

“We can already demonstrate in silicon a 30Gbps transmitter."

Is a datacom and telecom mini-boom taking place?

A reader commented that both semiconductor and optical transceiver lead-times are being extended and that the “good times are here”.  But what is the cause, he asked, and are good times really here?

Daryl Inniss believes it is largely a reflection of cutbacks that have run their course. “The industry cut back swiftly and deeply when the market started to tank, cutting suppliers and capacity,” says Inniss, practice leader, components at market research firm Ovum.

“I think it's recovery dynamics - people ordering a tiny bit more and there are no parts available such that lead-times are stretching out simulating a boom.”

Why optical transceiver vendors are like discus-throwers

Differentiation in a market that demands sameness

Transceiver feature: Part 2

At first sight, optical transceiver vendors have little scope for product differentiation. Modules are defined through a multi-source agreement (MSA) and used to transport specified protocols over predefined distances.

 

“Their attitude is let the big guys kill themselves at 40 and 100 Gig while they beat down costs"

Do multi-source agreements benefit the optical industry?

Transceiver feature: Part 1

System vendors may adore optical transceivers but there is a concern about how multi-source agreements originate. 

Optical transceiver form factors, defined through multi-source agreements (MSAs), benefit equipment vendors by ensuring there are several suppliers to choose from.  No longer must a system vendor develop its own or be locked in with a supplier.

“Personally, the MSA is the worst thing that has happened to the optical industry”
