RE: [802.3ae] WAN distance
Hi, Steve,
The 40 km maximum distance referred to is that
of a single link (i.e., one pair of fibers
between one pair of PHYs). What people do with
regenerators (O/E/O) is outside the scope of
the standard.
10GBASE-LW4 is no longer defined.
Cheers,

Subject: [802.3ae] WAN distance
Hi,
In WAN PHY , it states that the max distance is 40km.
But now the optical signal can be transmitted over
600km with O/E/O? why limit to 40km?
Is 10GBAse-LW4 still defined?
thanks
Steve
