Maiwei MW-2002(OR) - Optical Node
   Optical Node MW-2002(OR) series is a low price, high performance fiber node with one or two RF output (one hybrid for 1 or 2 output ports). It is widely used at node locations of a fiber optic link to convert the optical signal back to RF signal for distribution in the CATV cable plant.
 • 45~862MHz two-way broadband platform
 • Plug-in slope control circuit, optional split frequency
 • Up-stream upgradeable (with reverse transmitting path)
 • Optional Reverse Transmitting pad, easy upgrading.
 • Philips receiving module, superior reliability and performance
 • One GaAs (or Si) hybrids for post-stage amplifier use, with high output level (>100dBuV for 1 output port)
 • One or two RF output ports optional
 • With separate 5~200MHz up-stream
 • Optical power monitoring and high input power alarming
 • High efficiency Switch mode power supply
 • Easy maintenance, with -20dB test point, LED display for optical power indication.
