Accommodates a wide range of data transfer speeds
DT-55/50 series can handle a wide range of data transfer speeds from 25Mbps to an ultra-fast 1.25Gbps.
The user can selects the transfer speed according to the type of network in which the unit will be installed. |

Automatically adjusts the laser axis, providing stable communication
The DT-55/50 is equipped with an automatic tracking function that adjusts the laser axis to compensate for slight movements in the building or installation base due to temperature variations, or vibration due to wind. A CPU calculates the point of maximum light input and controls the laser axis appropriately. With up to 4 degrees of compensation in both the horizontal and vertical planes, this technology allows for maximum link availability. |
Principle of Auto - Tracking Function

Provides high-quality, reliable wireless communications up to 2km*
With an unobstructed line of sight and normal weather conditions, this laser network can provide instant, high-quality, highly reliable communications at a distance of up to 2km*.
* For DT-55, the maximum distance is 1 km.
For DT-50/DT-IF622, the maximum distance is 1.5 km.
The constant footprint function ensures maximum optical power at the receiver
Canon's knowledge and experience in the development and manufacturing of optical and laser technology have led to the creation of the constant footprint function.
This function ensures maximum optical power at the receiver.
Other laser transceivers allow the beam to spread with distance, reducing the link availability in adverse weather conditions. |

3R Function**
(Re-shaping, Re-timing, Re-generating)
The 3R function can be used to normalize the signal waveform with Gigabit Ethernet, Fast Ethernet, FDDI, and ATM (156Mbps, 622Mbps) transmissions in order to permit relay transmissions without deterioration of signal quality between buildings that are more than 2km* apart or that do not provide a good line of sight.
* For DT-55, the maximum distance is 1 km.
For DT-50/DT-IF622, the maximum distance is 1.5 km.
** Not available on DT-50/DT-IFFM1
"CMS" Canobeam Management Software
Proprietary Windows-based software which monitors the status of the DT-55/50 remotely is included. When an RS-232C cable is connected between the DT-55/50 and a PC, the status of the transceiver can be monitored and diagnostic logs can be stored in the PC. |
