MFL User Manual RIEF DESCRIPTION MFL provides wideband optical link for up to 4 RF channels combined in one single mode 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 chosen any combination of two types: • TX: Laser optical transmitter, (CDWM) plug‐in board • RX: Optical‐receiver plug‐in board Example of some possible configurations: ‐ MFL‐TTTT is a 4 laser transmitters on channel 51/53/55/57 (λ = 1510/1530/1550/1570 nm). ‐ MFL‐RRRR is a 4 optical receiver on channel 51/53/55/57 ‐ MFL‐RRTT has 2 receiver on ch. 51/53 and 2 transmitters ch. 55/57 (it works with MFL‐TTRR) ‐ MFL‐TTRR has 2 transmitter on ch51/53 and 2 receiver on ch. 55/57 (it works with MFL‐RRTT) Main features: CWDM LASERs to fit many RF channels over a single fiber 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 DIGITALLY TUNABLE FILTERS 25 MHz bandwidth, center frequency tunable over 404‐788 MHz (optional) INTEGRATED FAILSAFE REDUNDANCY: It can route RF through an external filter or to additional receiver (redundancy) to easily implement a failsafe configuration that can switch on a redundant receiver or transmitter if any fault is detected IFB MODE: It can route an IFB high power signal to transmit locally and send IFB carrier over fiber to slave units. When it is working along with a MTK952MS in slave configuration, the fiber loss is automatically recovered and the unit increases the gain so that the transmitter power equals the target level (measured with an power/SWR meter integrated into the MTK952MS) REMOTE MONITOR/CONTROL: thanks to a data link on Ethernet 10/100 Base Tx ...

MFL User Manual ISTEM VERVIEW 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 51 short name for wavelength 1510 nm ‐ Channel 53 short name for wavelength 1530 nm ‐ Channel 55 short name for wavelength 1550 nm ‐ Channel 57 short name for wavelength 1570 nm Channel Wavelength Color Identifier 51 Wavelength 1510 nm laser, single mode Blue 53 Wavelength 1530 nm laser, single mode Green Wavelength and Color Coding: 55 Wavelength 1550 nm laser, single mode Yellow 57 Wavelength 1570 nm laser, single mode Orange For example: NAME (i.e.) ...
