          CATV 4 Independent Output Series Optical Node With Reverse Transmitter    

Function:

 

Optical workstation / optical node applys for two-way interactive multifunction business requirement of HFC wide band network of fiber transmission system and meet the transmission requirement of CATV network business and telephone, data and value added services, etc.

 

Product advantage:

• 5-1000MHz optimization circuit design, frenquency bandwidth according to system customization.

  And it shall also be upgraded according to the using request.

• Specialized optical receiving module to receive, high working reliability.

• LED optical power meter, precisely show the input optical power

• Four way independent outputs.

• Output level can be 112dBuV.

• Good network management function, based on SNMP protocol, meet the national standard

• With local RF signal inject port or extended up link channel. The local analog or digital signal shall be mixed into network with local inject port. 

• New type die-casting aluminium casing, baking finishing or passivation process on the surface, shall work in outdoor mal-condition for long time.
