Canon's new CANOBEAM
DT-100 Series optical transceivers build on the outstanding
functionality of previous models, employing design innovations that
contribute to both reduced size and greater cost performance.
Featuring a compact optical module which integrates key optical
components in one tidy unit, and operates protocol independent, like
fiber optic cable, the models utilize advanced engineering to
realize size and weight reductions of up to 50% from previous
models. The units are available in several fiber or twisted pair
configurations, including Multi-mode (MM), Single-mode (SM) or
twisted pair (TP).
Fifteen years of Canon's free space optics (FSO) engineering
expertise is now available in their new DT-100 Series Canobeam, the
highly versatile optical beam transmission system. The fourth
generation of Canon's point-to-point optical beam transceivers
features:
- Built-In Auto
Tracking on Three New Models
- High speed transmission up to 1.25Gbps
- Optimized Size and Weight
- Highly Secure Data Link
- Protocol independent, like fiber optic cable
- No FCC Licensing or Radio Frequency
- Sleek design engineered with minimal space requirements.
- Affordable Price Without Compromise
- The DT-100 Series can withstand temperatures from -20 C to +50
C, wind gusts of up to 134 mph, and features a Weather-hardened
outer shell IEC-rated for permanent outdoor use.*
- Available in several fiber (MM: Multi-mode, SM: Single-mode)
configurations. DT-110 and DT-120 also available in twisted pair
(TP) configurations.
- DT-130 also available in MM and MM/SM configurations

| What is FSO? |
| |
Free-Space Optics (FSO) is a line-of-sight technology that uses
lasers to provide optical bandwidth connections. Currently, FSO
is capable of up to 2.5 Gbps of data, voice and video communications
through the air, allowing optical connectivity without requiring
fiber-optic cable or securing spectrum licenses. FSO requires light,
which can be focused by using either light emitting diodes (LEDs)
or lasers (light amplification by stimulated emission of radiation).
The use of lasers is a simple concept similar to optical transmissions
using fiber-optic cables; the only difference is the medium. Light
travels through air faster than it does through glass, so it is
fair to classify FSO as optical communications at the speed of light.
FSO technology is relatively simple. It's based on connectivity
between FSO units, each consisting of an optical transceiver with
a laser transmitter and a receiver to provide full duplex (bi-directional)
capability. Each FSO unit uses a high-power optical source (i.e.
laser), plus a lens that transmits light through the atmosphere
to another lens receiving the information. The receiving lens connects
to a high-sensitivity receiver via optical fiber. FSO technology
requires no spectrum licensing. FSO is easily upgradeable, and its
open interfaces support equipment from a variety of vendors, which
helps service providers protect their investment in embedded telecommunications
infrastructures. |

| History of FSO |
| |
| Originally used by the military and NASA, FSO has been used
for more than 30 years to provide fast communication links in
remote locations. Recent advances in FSO technology have opened
up mainstream communications uses, from short-term solutions
for short distance network bridges to an attractive and viable
alternative for service providers to deliver the promise of
all-optical networks. As an optical technology, FSO is a natural
extension of the metro optical network core, bringing cost-effective,
reliable and fast optical capacity to the network's edge. While
fiber-optic communication has gained acceptance in the telecommunications
industry, FSO communication is still relatively new. FSO enables
similar bandwidth transmission abilities as fiber optics,
using similar optical transmitters and receivers and even
enabling WDM like technolgies to operate through free space.
