Re: Cisco CRS with 100Gb line card

I wasn't aware of anyone doing single lambda 100G. Who's the vendor/manufacturer for those optics?

Alcatel-Lucent.

They arent "optics" as such, more trans/muxponders.

I've seen some of the equipment (carrier hotels), never been able to lay hands on it though (not my specialty/repsonsibility). Are the mux's still on the large side, or have they managed to shrink it a bit?

The ones Ive wroked with are the PSS-32 chassis, which is 19" wide an 13 or so RU (can just fit 3 of them in a rack). Ive worked more with muxponders than their transponders, and you can fit 5 of them in that chassis, so 50 x 10g = 500g line side per chassis x 3 = 1.5t per rack. Since the chassis is only about 300mm deep you can probably fit them front and back too.

Not sure if theres anything else more dense than that.

The one's I saw were 1/2 rack, so they've either shrunk somewhat, or have a lower capacity. Still, the amount of speed you have at the carrier level is amazing, I wonder what the link utilization is.
