ODN2000 / LE2000

Optical Distribution Node with two amplified RF ports

ODN2000 / LE2000

About the Product

The small and adaptable ODN2000 Optical Distribution Node with two amplified RF ports has been designed to affordably deliver interactive CATV and high capacity DOCSIS services. The ODN2000 is a high performance network device engineered to provide the highest quality transmission of HD video, data, and VoIP services. The LE2000 is the basic amplifier model and the LE2000 can be upgraded to a 2 port fiber node, ODN2000, by adding optional reverse transmitter module and forward receiver module. 

The ODN2000 is currently equipped with a GaAS module that offers a cost-effective and flexible solution to expand the network. The optical node offers two high power RF outputs, each with over 1 GHz of bandwidth. 

The ODN2000 deep-fiber node is perfect for the last mile in broadband networks. The small and rugged design makes this unit ideal for fiber-to-the-apartment and fiber-to-the-curb applications. Having versatile modular components allows the ODN2000 to be utilized in many different phases of network deployment. As the network grows, the ODN2000/LE2000 can be upgraded. Unmatched flexibility combined with a robust housing makes this a product that you can rely on when designing long-term HFC solutions. Additionally, Node +0 support allows for a reduction in amplifiers, improved reliability, and lower maintenance costs as well as providing additional options for future cost-effective upgrades.

The optional DOCSIS transponder eases maintenance by allowing for remote monitoring for alerts resulting in a reduction in potential expenses by using existing DOCSIS infrastructure for cable modems to carry information creating a smarter more efficient network. 

  • Advanced Gallium arsenide (GaAs) RF hybrid technology provides excellent performance with two individually amplified high-level outputs with more than 55 dBmV each at 1000 MHz
  • High output power supports Node +0 architecture
  • Can be seamlessly upgraded from an RF amplifier (LE2000) to an optical node (ODN2000)
  • Return-path lasers are available for 1310 nm or for CWDM applications on one return fiber at 1470/1490/1510/1530/1550/ 1570/1590/1610 nm
  • Optical transmitter/receiver modules and RF amplifier can be individually installed, removed, or replaced. The modular design reduces downtime and simplifies maintenance
  • Standard attenuator pad to control both attenuation and equalization
  • Dedicated KS 5/8" AC input for remote power. Auto-ranging 60/90 Vac power supply
  • Optional DOCSIS transponder to fully integrate forward and return path transmission signals
  • Remotely (future) or locally manageable and upgradable
  • Future forward path receivers and return-path transmitters will support forward and return-path segmentation
  • Future forward path receivers and return-path transmitters will provide redundancy protection
