SYSTEM 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
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
Wavelength and Color Coding:
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-RRTT has 2 receivers on ch. 51/53 and 2 transmitters ch. 55/57 (it works with MFL-TTRR)
- MFL-TTRR has 2 transmitters on ch51/53 and 2 receivers on ch. 55/57 (it works with MFL-RRTT)
- MFL-TT-- has 2 transmitters on ch51/53
