MERRIMACK, N.H. -- Metrobility Optical Systems, a leading provider of intelligent, carrier-class optical Ethernet solutions, today introduced the Bi-directional Wavelength Division Multiplexer (BWDM) which utilizes two separate wavelengths to carry two distinct channels in different directions on a single strand of fiber. Bi-directional fiber connectivity improves network scalability and serviceability and is ideal for both MAN and LAN applications where additional users must be supported on existing fiber connections. BWDM eliminates the need to install a second fiber and effectively doubles the fiber capacity on existing fiber cables. The BWDM Interface converts electrical signals to wavelengths on a single strand of fiber, and provides a manageable, cost effective solution to achieve distances up to 20km. At one end of the connection one wavelength (e.g., 1310nm or 1550nm) is used to transmit, and another wavelength (e.g., 1310nm or 1550 nm) is used to receive. "We believe that many businesses will choose this BWDM solution as a cost effective alternative to installing additional fiber, especially between buildings," said Alex Saunders, president and CEO of Metrobility Optical Systems. "BWDM provides a 100% improvement in fiber utilization since only a single fiber strand is required. Thus, fiber costs, installations costs, and maintenance costs all reduce the overall cost of ownership." Metrobility Optical Systems
