One of the sidebars from the shorthaul DWDM article: Sayonara, Sonet-or Don't Wait for the Wave? Some say DWDM runs rings around Sonet. Others are on a completely different wavelength. Here's why DWDM might replace Sonet-and why synchronous optical networking might just stick around. DWDM... ...promises the possibility of just-in-time provisioning for high-speed corporate data traffic ...handles enterprise apps like Escon, Fibre Channel, and gigabit Ethernet ...scales to dozens of OC48 (2.488-Gbit/s) trunks Sonet... ...is well known: Millions of dollars have been invested in it and carriers have been managing it for a decade ...supports more intelligent features than DWDM, like bidirectional line-switched rings and time-slot/wavelength assignment ...offers the multiplexing needed for services lower than OC12 (622 Mbit/s), which are too expensive to carry on wavelengths ...makes for a less expensive upgrade, since pulling new fiber is cheaper in many areas than moving to DWDM
