Code 270657


Three-input OPT-MBJ optical transmitter for distribution of band 3, UHF and full IF-IF signals on a single fibre. Laser optical output level of 5dBm, wavelength 1550nm. (dimensions 135x82x39mm)

Technical chars

  • OPT 3US TX: Up to 20dB of manageable optical attenuation (division ratio greater than 1:32 over P.O.N. distribution) when TX is used together with OPT-RX receiver.
  • A.B.L.A. Technology: this exclusive FRACARRO system maintains the correct optical level via special independent electronic circuits, even if the RF input level of each input changes
  • Dedicated A.B.L.A. status LEDs
  • Separate amplification: the new OPT-MBJ optical transmitter works with "separate amplification" and independent handling of the RF input signals
  • Protective shell: OPT-MBJ optical transmitters and receivers are protected by an innovative protective shell made of flame retardant ABS material (Class V0)
  • Optical output level stabilisation even for high variations of the RF input signal
  • Monitor output: RF output connector for monitoring the RF signal without disconnecting the service from the distribution network
  • Suitable for standard DIN rail mounting (with quick release)
  • Low power consumption
  • Power supply status LED
  • Quick and easy installation (Plug&Play)
  • High shielding against electromagnetic interference
  • Standard SC/APC connectors
