Overview
The Metrobility
®
Radiance T3/E3 line card provides high-speed integration
and conversion of T3 (44.736Mpbs) or E3 (34.368Mbps) coaxial telco commu-
nication lines to fiber transport environments. The copper data stream is con-
verted to optical signals for greater noise immunity and longer transmission. The
T3/E3 line card supports remote fiber optic links up to 2km over multimode and
up to 100km over singlemode cable.
To optimize your T3/E3 network, this hot-swappable media converter operates
seamlessly with low jitter. All signal activity is completely converted ensuring
accurate communication within connected segments. The Radiance T3 line card
features a user-selectable line build out, and all T3 and E3 models include
independent copper and fiber loopback modes to isolate problems within a
specific segment of the network.
Management options supported by the Radiance line cards include terminal
console commands, Metrobility’s GUI-based NetBeacon
®
or WebBeacon
software, or any standard SNMP application. This ability provides remote
control over the line card’s configuration and immediate notification of a
problem to a management station.
The Radiance T3/E3 line card offers the following key features:
• B3ZS (T3) or HDB3 (E3) line code support on the coaxial interface.
• System and port LEDs on the front panel for easy diagnostics.
• Independent copper or fiber loopback mode that can be set with a DIP
switch or through software via local management.
• Individual port enable/disable.
• Line build out switch for short- or long-haul operation on the T3
models.
• Coaxial to multimode conversion up to 2km, coaxial to singlemode
conversion up to 100km, or coaxial to bidirectional wavelength
division multiplexed (BWDM) conversion up to 20km.
• Surge protection on the RX and TX ports of the coaxial interface.
• Low jitter for maximum transmission quality.
• Independent clocking on the RX and TX ports.
• Hot swappable.
• High MTBF.
