New product features are continuously being added to Transition Networks's products.
These improvements are also available for many products already installed in the field.
Management modules and many media converters can be updated remotely via
firmware upgrade. The remote upgrade feature eliminates the need to ship the
products back to the manufacturer. The firmware upgrades can be performed by a user
either locally via a Console port or remotely via TFTP. 

The upgrades do not require the reconfiguration of the SNMP management or
converter feature settings.



Single fiber technology offers a 50%
savings in fiber utilization. It is an
attractive solution to maximize the
usage of a limited number of fiber runs.

In a traditional optical link, a fiber pair
consists of two uni-directional strands.
The single fiber technology multiplexes
two optical wavelengths of 1310nm and
1550nm into a single strand fiber. In a
single fiber media converter each
wavelength is responsible for either the
transmit or receive function.
Consequently, the bi-directional
transmission is achieved by using a
single strand. The converters in a single
fiber scenario "match" each other's
wavelengths. Converter A transmits at
the wavelength of 1310nm and receives
at 1550nm while the other converter
transmits at 1550nm and receives at
1310nm. Therefore, converters are
usually used in pairs.

Single fiber technology is available on
all Transition Networks Media
Converters in maximum distance ranges
from 20 to 80km.
