  • Smallest full-featured CATV node on the market!
  • 50 to 870MHz forward bandwidth accommodates up to 110 channels on all models.
  • Up to +38dBmV RF output signal over the entire optical input range, allowing a greater number of drops or splits.
  • Excellent CATV performance with CNR up to 54.5dB, CSO of -63dB, and CTB of -66dB.
  • Ultra-wide usable optical input range, -8dBm to +4.5dBm, permits the use of a lower power transmitter, lowering system cost.
  • Built-In digital optical power meter for easy setup and maintenance.
  • Capable of responding to changing system requirements with field-installable return path modules.
  • Digitally adjustable built-in RF attenuator and equalizer settings allow for accurate adjustment of parameters via front panel buttons and the LCD screen.
  • SC/APC optical connector standard. FC/APC option available (contact factory)


The Olson OTPN-MDN-870 Fiber Optic Mini Digital Node (MDN) provides CATV headend operators with a unique node with an extensive array of features, small size and low-cost. The MDN is fully compatible with Olson’s line of forward path transmitters and return path receivers. The MDN provides an output of +38 dBmV of RF over the entire optical input range, allowing multiple RF splits without the use of an external RF amplifier. The Mini Digital Node is unique because it operates over a ultra-wide optical input range of 8dBm to +4.5dBm without degrading performance. A unique built-in LCD display and digital control buttons allow the operator to quickly and easily set the tilt and RF output levels of the unit. There is no need to open the MDN to replace fixed pads and equalizers. The unit remembers specific settings even if power is lost. The OTPN-MDN-870 can be ordered either with or without a return path module. The return path module may also be ordered separately, allowing for a quick factory upgrade or laser replacement. The return path module utilizes a wide variety of laser types including 1310nm FP, 1310nm DFB, 1550nm DFB and CWDM DFB lasers. The modular design of the MDN offers unparalleled flexibility and performance demanded by today’s broadband professional. The unit includes separate -20dB test points for the forward and reverse RF signals. An alarm signal and an analog signal proportional to the light level are also provided. The node ships with the mating universal AC power supply.
