RF Fiber Optical Transmitter 2mW 45-750/862/1003 MHz

L-RF-2mW-TX

The QuestTel's 1310nm - 2mW direct modulated optical transmitter is the most important equipment to construct the CATV HFC network. It mainly used for the long distance optical fiber transmission of TV image signal, digital television signal, telephone voice signal and data (or compressed data) signals.

  • Adopt high-performance coaxial/butterfly DFB laser, narrow spectral lines, good
    linearity and high output power.
  • Supports broadband range 45-750/862/1003 MHz
  • The RF drive part adopts the RF power digital automatic processing technology.
    Automatic processing the drive level power according to the RF input signal level
    and the number of channels (15-84 channels), make the CSO, CTB and C/N index
    always at the optimal value to ensure the overall performance.
  • Advanced multi-frequency RF pre-distortion technology, combined with the GaAs
    device, effectively improve the CATV system most important CTB and CSO
    index, C/N index also gets the maximum upgrade.
  • Adopt advanced 32 bit processor; coordinate with perfect automatic monitoring
    system circuit. It can timely and accurately monitor working status of the laser to
    ensure a stable optical output power and effectively extend the working life of the
    laser.
  • Built-in blue screen 160×32 dot matrix LCD monitor on the front panel,
    accurately showing all working status parameters.
  • Automatic Gain Control (AGC) manages RF level with no adjustment needed
  • 19″1U standard rack mount, equipped standard IEEE802.3 10Base-T Ethernet
    interface and RS232 interface, can expediently realize network management
    monitoring.
  • Outputs Industry standard RFoG (RF over Glass)
  • Fully support specification GB/T 20030-2005 HFC Network device management system
    specification.

The QuestTel's 1310nm - 2mW direct modulated optical transmitter is the most important equipment to construct the CATV HFC network. It mainly used for the long distance optical fiber transmission of TV image signal, digital television signal, telephone voice signal and data (or compressed data) signals. It converts any incoming RF signal within this band to optical RF and transports all channels and programs over one fiber. This product does use the high-performance DFB laser as the optical source with Automatic Gain Control. The RF drive part adopts RF power digital automatic processing technology and advanced RF pre-distortion circuit, and built-in microcomputer automatic monitoring system, to ensure the excellent performance indicators.
