RE: long distance gigabit ethernet

  • From: Chen Genossar

Hi Greg,

Are you familiar with companies that provide two gig Ethernets into an OC-48
channel ?

Best Regard

One thing to consider here is that you have to buy and OC-192 service
for 10GbE WAN phy.  That is prohibitively expensive for many.

Also, be sure to ask Ethernet vendors about their time frames for WAN
PHY support.  While there is a spec for WAN PHY, there has been a
disconnect between the telco and ethernet oriented industries about
which PHY will make money for them the fastest.  Ethernet vendors in
the 10G space typically provide LAN PHY now with vauge plans for WAN
phy over the next 18 months.  There are exceptions already and this
will resolve over time.  However, if you are seriously looking at
10GigE today, this is worth spending some time on.

For GbE, another direction to look at is the DWDM products that can
feed two gig ethernets into an OC-48 channel.
