Transition Networks's converters will automatically re-establish link in all network conditions.

Transition Networks's converters will automatically re-establish link when connected to switches if link was
lost. With other manufacturers' converters the user must reset the converter to re-establish the link.

Automatic Link Restoration allows the users to continue using Auto-Negotiation with Link Loss Notification
features. With other manufacturers' converters the user must disable Auto-Negotiation and hard set the link.

Automatic Link Restoration on Transition Networks's products allows users to continue using Link Loss
Notification feature activated in both directions. Many competitive solutions allow for Link Loss Notification
activation only in one direction. If Link Loss feature is activated in both directions, competitive products are
put in a "deadly embrace" and they cannot restore the link without resetting the converters.

No need to reset devices

Auto-Negotiation Enabled

Link Pass Through Activated in both directions

PAUSE signaling is an IEEE feature that

temporarily suspends data transmission

between two devices in the event that

one of the devices becomes

overwhelmed. In the event that a device

needs some time to clear network

congestion, it will send out a PAUSE

signal to the other end device, which will

then wait a pre-determined amount of

time before re-transmitting the data.

Transition's converters will pass PAUSE

signaling unhindered; ensuring that the

message is delivered to the end device.

PAUSE signaling is not standardized

over fiber media. Transition's media

converters will communicate this

signaling over fiber between the

converters to pass this signaling on to

the other end device.

PAUSE enabled devices allowed to work

properly

Prevents loss of valuable data

transmission

Reduces bottlenecks and allows for

efficient use of network devices

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.
