2*8mw SBS Tunable 1550nm External Modulated Optical Transmitter for CATV

The 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: CNR>52dB, CSO>65dB, CTB>65dB
●Standard 45MHz~1005MHz bandwidth, compatible with digital TV
●Unique CSO Auto adjust circuit, CTB pre-distortion circuit
●Perfect SBS Control: Chirp and SPM both
●Unique technology balance the contradiction between SBS threshold and dispersion
●Long distance transmission up to 140km
●Flexible for networking: SBS 13dBm~20dBm can be adjusted
●Perfect network interface: Support SNMP and Telnet
●Wide range RF control technique: AGC , MGC is optional
●Used for DWDM system and dispersion compensation
●ITU-T wavelength is optional and adjustable
●Dual power supply
