For the selection of a suitable
FSO system it is only necessary to determine
- the desired transmission speed of the planned link
- the rough air-line distance between the buildings
The following OPTICOMM systems are offered:
OPTICOMM-FDD systems are designed for
high-speed LAN protocols. They
offer multimode F/O interfaces and a transparent full duplex
signal transmission
bandwidth of 500 kbps to 155 Mbps, suitable for Fast Ethernet,
FDDI and ATM
networking protocols.
OPTICOMM-FDD/HS systems have the same
bandwidth, incorporate however
a single-mode F/O interface for medium and long distance
components in PDH
and SDH applications.
OPTICOMM-DUAL systems are genuine 2-channel
systems, incorporating two
independent multimode F/O interfaces. Both channels provide
a transparent full
duplex signal transmission bandwidth of 200 kbps to 20 Mbps.
This allows LAN connections employing low-speed LAN protocols,
parallel to G.703 T1/E1 telephone exchange links.
OPTICOMM-DUAL/HS systems also offer two
independent full duplex channels.
However, one high-speed channel has a transparent signal
transmission
bandwidth of 500 kbps to 155 Mbps, the other channel a bandwidth
of 200 kbps
to 4 Mbps. This allows high-speed LAN connections using
Fast Ethernet, FDDI or ATM
protocols, parallel to G.703 T1/E1 telephone exchange links.
The systems OPTICOMM-VIDEO are employed
in security applications and allow parallel transmission
of video and audio signals as well as digital data.
All OPTICOMM systems are available in four performance
classes:
| Model |
Min. Distance |
max. Distance |
| OC-XX 400 |
10 m |
400 m |
| OC-XX 1000 |
50 m |
1000 m |
| OC-XX 2000 |
50 m |
2000 m |
| OC-XX 4000 |
250 m |
4000 m |
Systems of a higher performance class offer higher link
availabilities due to
higher power margins, if installed at the same distance.
