Infinera 100G Checkup
Infinera is sticking to its timeline of producing 500-Gbit/s coherent photonic integrated circuits (PICs) in 2012. In the interim, a non-PIC, 40-Gbit/s card will come out in 2011. (See Infinera Ditches 40G, Talks 100G.)
What Infinera is not talking about is the nature of the 500-Gbit/s PIC -- whether the five channels comprise two optical carriers apiece. The channels do fit within 50GHz spacing, says Dave Welch, Infinera's chief strategy officer. But what we've heard is that the PIC will initially use two 50-Gbit/s carriers -- two wavelengths inside a 50GHz slot -- to produce 100 Gbit/s, just as Ciena Corp. (NYSE: CIEN) is doing with the old Nortel Networks Ltd. gear. (See Infinera Puts 100G Coherent on Pause and Verizon Switches On 100G in Europe.)
On a not-so-related note: You've seen the picture of Heavy Reading analyst Sterling Perrin in the bunny suit, right? Not the long-eared kind (we'd need to feed him more beers first) but the semiconductor fab kind. His writeup takes you on a tour of what goes on inside a fab. Check it out: A Peek Into Infinera's PICs.
