|Gross data rate
||Full duplex only
||1.4km with HPWT-BD00-F4000 and 130mm lenses. See Range
Issues for more details.
The switch or cad has to have well implemented PLL.
|Minimum operating distance
||1/4 of nominal range. Further manual reduction possible by
change of two passive components in receiver.
||IEEE 802.3 Attachment Unit Interface (AUI). Connector male
DB-15 with screws instead of AUI mechanical latch. AUI cable not
supported - integrated cable length 1m. The preamble is chopped off more than
specified by IEEE 802.3 which could cause a problem when Ronja is connected
into a cascade of pure hubs. However hubs almost don't exist today anymore
so it is not a problem.
||300mA @12VDC (3.6W) from AUI, 2W from external heating power
supply (switchable off)
||visible, 625nm, 100nm spectral width (618nm perceived
|Divergence cone half angle
||1.9mrad (130mm aperture transmitter lens)
|Estimated Optical EIRP
||20kW (130mm aperture transmitter lens, HPWT-BD00-F4000)
||-30…+70°C (outdoor part - optical heads, RX, TX),
0…+55°C (indoor part - AUI interface)
||up to 100% (condensing) with lens heating on, up to 95% with
lens heating off.
||15.5kg (one side of a link, on a welded parallel console)|
||4km for uninterrupted operation at full range. See Distance Issues for more information.
||BPSK (as on AUI) plus 1MHz asynchronous 50% duty cycle square
wave between packets. The transmitter appears to shine permanently
and steadily no matter if data pass or not.
||Power, Receive Packet, Transmit Packet
||visual, retroreflector for transmitter and DC voltage signal
strength monitor port for receiver.
|Fine aiming gear ratio
||Complies with Czech
State regulation: 480/2000 Col. Government Direction about Health Protection
from Non-ionizing Radiation
|Mechanical Installation Constraints
- Possible mount places:
|Place||Is drilling necessary?|
|Railing, round or rectangular||No|
|Corner of wall||Yes|
|Horizontal or tilted surface of masonry or masonry covered with
tin, foil etc.||Yes|
- Max. 1m from AUI connector is a grounded metal box with
dimensions 160x140x52 mm.
- Cable distance between AUI connector and optical head mounting
points is max. 100m
|EMI and safety installation constraints
- Cable may be laid directly along sources of interference (other
signal and power cables)
- Cable doesn't radiate interference
- Optical heads may be mounted even on places where lightning
strike hazard exists.
