10mW Direct Modulation 1550nm Optical Transmitter CATV Laser Fiber Optical Transmitter
Product Features:
---1U 19” rack, stainless steel housing with excellent heat dissipation and appearance.
---The bandwidth 47-862MHz, also 1000MHz can be customized.
---Adopt world top brand laser with wide bandwidth and high output power.
---Built in microcomputer automatic monitoring circuit, real-time monitoring the optical output power and laser working state. To ensure the stable output power and expand the laser lifespan.
---Advanced multi-frequency RF pre-distortion technology, RF GaAs devices and complete SMT structure effectively improve the C/N, CTB and CSO parameters in the CATV system.
---RF driving circuit adopts the RF power digital automatic processing technology. According to RF input signal level and the input channels number, automatically handles the driveing level, in order to keep the C / CTB, C / CSO and C / N parameters always in the best status.
---Laser automatic temperature stabilization circuit (ATC) and optical power output stabilization circuit (APC), ensure the laser working with optimal performance.
---RF output power detector and the RF relay shutdown function effectively prevent the damage of the laser when the signal is too high. AGC / MGC working mode for optional.
---The front panel has working status indicators and the back panel has RF test port.
---The working parameters and fault information can be displayed through centralized monitoring unit on the LCD screen, also can monitor through RJ45 network interface.
