Peter,

Currently the 15454 supports, via its SONET cross-connect, GigE and OC-192 interfaces. This means that all packets and STS-1 must go through the cross-connect and come out as an ITU wavelength at OC-192. We call this ITU card the 10G TDM ITU. This summer we will release 3 transponders that do not use the cross connect. Not using the cross connect is termed "wavelength service". The transponders are not released yet therefore they are not on Cisco.com.

The three models of transponders are:

  1. 10Gb Multi-rate Transponder: OC-192/STM-64/10GE LAN PHY/10GE WAN PHY. Does any 10Gb data rate via software selection.
  2. 4 x OC-48 Muxponder. This takes 4 OC-48 signals and combines them to an OC-192 wavelength
  3. Multi-rate transponder: Takes any NRZ formatted signal between 150Mb and 2.5Gb and places it on a 2.5Gb wavelength. Supported rates include OC-3/12/48, GbE (SX or LX), Fibre Channel, ESCON, HDTV, DV6000, D1 Video. To change the data rate, you just plug in a new SFP transceiver. We sell SFPs for each rate listed above.
For NCAR I will quote a 10Gb Multi-rate Transponder (10GE application) and a Multi-rate Transponder (GE) for each 15454 terminal site. For the GE I will quote the LX and SX SFP too.

For your application we would use wavelength services as it is cheaper than installing the cross-connects AND the 10G TDM ITU.

As soon as you get the fiber information I will send you the quote.

Regards,

Russ
