ATM or OC-3 or Fast Ethernet Networks
Save money by purchasing Fast Ethernet devices with lower cost multimode fiber interfaces and use converters to introduce single mode fiber only where you need it.
Extend distances up to 80 km over single mode fiber with these network protocols that use 1300nm wavelength for fiber optic transmission. In fact, distances can be extended in any 155 Mbps networking protocol.
Extend a Fast Ethernet backbone connection up to 80 km for MAN (metropolitan area network) applications.
