RE: Long distance links
Roy:
Although there is no 802.3 WAN standard we do have GbE switches from vendors
that have 23 db lasers ( i.e. will drive over 100 km on G.652 fiber). The
more common alternative is to use Gbe laser transceivers from a number of
suppliers. These also come with 20-23 db lasers
No co-location space is required except at the node where the customer's
fiber interconnects to a DWDM channel, currently IP over SONET
Shortly we are issuing an RFP for a "customer empowered network". Please
send me an e-mail for those who are interested in a draft copy
