Motorola OmniStar GX2 GX2-OA100B Series Optical Amplifiers for HFC Networks

 

 

Motorola's OmniStar GX2-OA100B Series erbium-doped optical amplifiers serve multiple applications for HFC networks including super-trunking, direct distribution to many nodes, and DWDM narrowcast and return. The GX2-OA100B Series  optical  amplifiers are designed for use with the OmniStar® GX2 1550 nm broadcast transmitters and DWDM transmitters. With adjustable output and several nominal output powers available, the GX2-OA100B Series accommodates a wide range of link budgets. Its three operating modes can satisfy a wide range of system design requirements: Constant Output Power mode to maintain exact optical levels; Constant Pump Power mode to optimize noise figures; and Constant Gain mode for DWDM applications.  The GX2-OA100B Series Optical Amplifiers employ a proprietary erbium-doped fiber formulation that provides low noise performance, along with the most reliable pump lasers available in the industry.

 

Other user benefits offered as part of the OmniStar  GX2 platform include: higher density, SNMP interface for network management, and Quick-Swap module capability

1550NM & Transmitter

 

The Motorola's GX2-EM870 series of 1550 nm Broadcast Transmitters uses advanced optical linearization technology to provide low noise and superior distortion performance. The suite of products satisfies various applications: full band loading or split band loading, super-trunking or distribution to nodes, long-distance transport or short hops. Several different versions of the transmitter are available that are optimized for transmission system standards with 6 MHz, 7 MHz, and 8 MHz video channels.

The transmitter uses a 1550 nm DFB laser diode as a precision light source, which is modulated by an optically linearized Mach-Zehnder modulator. Use of external modulation technology eliminates laser chirp and allows designs of transport systems for distances well beyond 100 kilometers.

Specification

  • Provides full performance 50 - 870 MHz forward bandwidth.
  • Designed for combined analog/digital operation.
  • SBS suppression up to 16 dBm.
  • Test point for RF input.

 

Applications

  • Supertrunking.

CATV OPTICAL  TRANSMITTERS

 

Hollands optical transmitters offer great flexibility to meet the demands of  today's CATV requirements. The   NE1000 Series transmitters are ideal for  offering a combination of analog  and  digital content.  These  transmitters  utilize a directly-modulated  1310nm DFB  laser diode and superior circuit design supporting automatic temperature and power control. Features  include gain control (both AGC  or  MGC)  for  RF input level, and excellent linearity due to patented pre-dis- tortion technology. The   NE1000  Series transmitters are an ideal solution for today's medium sized CATV system offering a wide array of services.
