Read moreabout the condition Brand: QuestTel CATV 4 mW RF Optical Transmitter 45-750/862/1003 MHz The QuestTel's 1310nm - 4mW 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) signal's. 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. Features Adopt high-performance coaxial/butterfly DFB laser, narrow spectral lines, good linearity and high output power.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 needed19″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.
