• Overview

Networks grow where they’re needed, not necessarily where it’s convenient. Where physical barriers, zoning laws, or other factors stand in the way of extending your network, Canon offers a solution. Canobeam DT-55 can create a gigabit ethernet, low-cost data connection across a straight-line distance of up to Km.

Here is what you need to know about Canobeam DT-55.

• Supports TCP/IP with an option for SNMP.
• Lower installation and maintenance costs than fiber optic cables.
• Canobeam DT-55’s "untappable" transmissions are highly secure.
• 3R technology allows relay of the data signal without loss of signal strength and quality.
• Autotracking technology means that alignment between units will be maintained even under conditions in which buildings or other platforms move due to altitude or wind conditions.
• Constant footprint function adjusts the beam according to the distance it must travel, maintaining beam focus and signal strength over the full range of transmissible distances.

Canon has developed this product over ten years, and has built a record of success for the product series. And, behind Canobeam technology is all of Canon’s Know-How in optics, data, and networking technology.

• Features

Integrability-Security-Reliability Ethernet

Canobeam DT-55 is designed to work with IT system administrators as a complete solution that includes scalability, performance monitoring, security, and flexible integration into the network. The Canobeam includes CanobheadNeweam Management Software as a standard configuration that monitors the status of the Canobeam DT-55 on a remote PC. And, the point-to-point wireless optical beam transmissions of the Canobeam DT-55 are highly secure, "untappable" connections. Canobeam DT-55 works well in areas where there is high radio or other EMR interference. There is no necessity of radio frequency permits, allocations, or licenses.

Cost Control

Canobeam DT-55 has operating and initial costs that are, in most applications, much lower than those associated with the installation of fiber-optic cables, or lower-speed monthly paid services such as DS-3, OC-3 or OC-12.

The 3R and Constant Footprint Functions

Where there is no direct line of sight between the two proposed points of communication, or where the distance required exceeds KM, multiple Canobeam units can be placed to relay the signal from its point of origin to its destination. The 3R function, (Re-generating, Re-timing, Re-shaping) normalizes the signal waveform so there is no deterioration of the signal during relay transmission.

Autotracking

Building sway, platform movement, wind, and other factors can cause any installed device to vary from its original position. Canobeam DT-55 protects the data stream from interruption by compensating for any variation of up to 4 degrees. Devices without this feature experience serious limitations in how they can be implemented.

Optional SNMP Interface Board

The optional SNMP interface board for the Canobeam III / DT-50 allows the network administrator to employ the unified, centralized control of network operations which is made possible by Simple Network Management Protocol (SNMP) when managing the Canobeam III / DT-50 as part of the network. The Canobeam III / DT-50 unit can be managed under SNMP from a personal computer. Reduce management workload, while increasing speed and flexibility of response to the needs of your network.

• FAQs

Is the performance of the beam affected by weather?

As a general rule, Canobeam DT55 will perform well if the units are visible to one another, even in bad weather conditions. However, the effects of weather on optical beams should be considered. Rain, fog, and snow reduce, scatter light, and lessen the amount of light that passes between the units. Since this can result in errors, a backup line is recommended.

The constant footprint and auto tracking functions give the Canobeam DT55 a strong advantage over other comparable products without these features.

Are the lasers safe?

The Canobeam DT55 uses class 1B lasers. The laser light output by these units is safe even if viewed with the naked eye at the point of output for up to seven minutes. The use of magnifying optics is not recommended, as the effect to the eye through these devices will be stronger.

What happens if a bird flies across the path of the laser?

If the laser beam is partly obstructed by a bird flying across its path, the amount of light passing between the units will be briefly reduced but there will still be adequate light for data transmission. If a bird obstructs the beam completely, the data will be momentarily interrupted but the problem will be resolved by a retransmission of the data since TCP/IP is used.

Is a relay setup possible?

For network connections between buildings that are more than 1 kilometer apart, or that do not have a clear line of sight, pairs of CANOBEAM units can be connected to relay the signal. Because the waveform is normalized by the 3R function at each relay point, the data is not damaged by the relay process.
