4 Metrobility 10/100Mbps Delta Class AutoTwister
Overview
Sleek, compact, and rich in features, Metrobility’s 10/100Mbps Delta
Class AutoTwister looks as great as it operates. Designed for desktop
use in any modern office, the durable AutoTwister meets strict US and
international EMC regulations. This versatile device allows you to extend
copper-based network distances up to 100km, connect 10Mbps devices
to 100Mbps devices, and convert from copper to fiber as well as from
half to full duplex. New features include a wall mounting option, highly
visible LEDs on the top, and built-in cable management and protection.
To eliminate trips by network technicians to physically reset the unit
following a link failure, the AutoTwister includes auto-recovery to auto-
matically restore link on the fiber line after a link loss event. Auto-recov-
ery works in conjunction with Link Loss Return and Link Loss Carry
Forward, two additional troubleshooting aids provided to identify the loss
of a remote network connection.
On select models, bidirectional wavelength division multiplexing (BWDM)
offers an interface that carries two separate channels in different directions
through a single strand of fiber. BWDM eliminates the need to install a
second fiber and effectively doubles the fiber capacity on existing fiber cables.
