Ronja 10M Metropolis Technical Specification

Bit rate and transmission mode: 10Mbit, full duplex
Maximum operating distance: 1km wih 130mm lenses, 500m with 90mm lenses.
Minimum operating distance: 1/15 of maximum operating distance. Further manual reduction possible by change of two passive components.
Data interface: IEEE 802.3 Attachment Unit Interface (AUI) except mechanical latch requirement
Power consumption: 300mA @12V (3.6W) from AUI, 2W from external heating power supply (switchable off)
Operating wavelength: visible, 625nm, 100nm spectral width (618nm perceived wavelength, red-orange)
Estimated optical output: 12mW
Divergence cone half angle: 1.9mrad (130mm aperture transmitter lens)
Estimated Optical EIRP: 10kW (130mm aperture transmitter lens)
Operating humidity: up to 100% with lens heating on, up to 95% with lens heating off. Certain atmospheric visibility required.
Optical modulation: BPSK (as on AUI) plus 1MHz asynchronous 50% duty cycle square wave between packets.
Indicators: Power, Receive Packet, Transmit Packet
Aiming system: visual, retroreflector for transmitter and DC voltage signal strength monitor port for receiver.
