2×8mW SBS Tunable 1550nm External Modulation CATV Optical Transmitter
External Modulation Optical Transmitter is designed for analog CATV system, it has highest cost performance in CATV long haul, Large distribution networks. Nonlinear effect, especial CSO, in analog LiNbO3 modulation is ensured by unique Auto Bias Control circuit (ABC), employing PLL tracking.
Employing chirp effect to co-operate SPM effect to suppress SBS, make the contradiction of SBS with dispersion get to minimum, and the threshold of SBS can up to 20dBm. Excellent flatness, return loss, etc, is given by exact match on RF circuit. And, professional pre-distortion circuit for LiNbO3 modulator make the best CTB. Better stability and shorter MTTR is brought by redundancy hot swap power designing. It has been Excellent Network management performance by SNMP and Telnet.
Features Excellent Transmission performance index Perfect SBS Control: Chirp and SPM both ITU-T wavelength is optional and adjustable Used for DWDM system and dispersion compensation Wide range RF control technique: Optional AGC, MGCStandard 45MHz~860MHz bandwidth, digital TV compatible | Application High Power Distribution Networks High Performance Supertrunking LinksRedundant Ring ArchitecturesDWDM Node SplittingVideo Optical transmissionAnalog, Digital CATV Long-haul system |
