MFL provides wideband optical link for up to 4 RF channels combined in a single fiber thanks to CWDM technology.
It is designed to allow for a flexible and modular configuration thanks to a mainboard that can be fitted with up to 4 plug-in boards that can be any combination of two types:
Example: MFL-TTTT is 4 laser transmitter unit that works with a MFL-RRRR with 4 channel receiver. Other configurations are also possible like MFL-RR / MFL-TT or a mixed like a MFL-RRTT with both receiver and transmitter channels.
The system is composed by a MFL-BASE (1U rack frame) and some optional/modular boards to build the desired configuration.
MFL-BASE can have up to 4 optical modules that can be either TX or RX (factory installed) to adapt the unit to several configurations.
To simplify the usage we give a name of the final configuration that easy identify the CWDM channels and a color code for the RF connectors (N type).
We use as default 4 laser wavelength although the CWDM standard can allow to use much more with a 20nm wavelength separation:
Channel | Wavelength | Color Identifier |
51 | Wavelength 1510 nm laser, single mode | Blue |
53 | Wavelength 1530 nm laser, single mode | Green |
55 | Wavelength 1550 nm laser, single mode | Yellow |
57 | Wavelength 1570 nm laser, single mode | Orange |
For example:
Following the main code and option that can build up a MFL system:
| # | Code | Description |
1 | MFL-BASE | WIDEBAND RF OVER FIBER MAINBOARD 19' 1U Rack units , aluminium frame Oled display - Ethernet - failsafe switch - realtime clock AC Powered 230V | |
2 | MFL-RX | Optical RX module for MFL (CWDM) | |
3 | MFL-TX | Laser TX module for MFL (CWDM) | |
Optional | 4 | MFL-DC | Insulated DC power with battery monitor (10÷28Vdc) |
5 | MFL-OMX | Module Mux/Demux for 1:4 CWDM | |
6 | MFL-BF1 | RF filter 25MHz tuning range over 404÷788 MHz |
LOW NOISE DESIGN to allow great coverage when used to remote receiving antennas
HIGH INTERFERENCE IMMUNITY thanks to high IIP3 design and a control/compensation of gain
EASY TO USE thanks to integrated RF/optical power meter and optical power compensation
REAL-TIME CLOCK with a backed-up static RAM to monitor and record internal RF levels and service data (i.e. laser life time)
TX UNIT (remote RF reception, i.e. diversity antennas):
RX UNIT (RF transmission, i.e. single-frequency master/slave areas)
REMOTE MONITOR/CONTROL thanks to a data link on Ethernet 10/100 Base Tx
RF INPUT / OUTPUT
