1550nm Externally Modulated Optical Transmitter

Product Description

Product Description Product description ***0nm externally modulated technology has no laser chirp, low dispersion distortion, and great extinction rate, with excellent characteristic within *0~**2MHz. External Modulator doesn't generate CSO distortion after reasonable bias. It can be followed by amplifier when used in large area coverage of over-long trunk and local networks. Adopting WDM, it can multiplex optical channels with multi-wavelength through one fiber. ***0nm optical fiber CATV follows the current development trend of triple-play and fiber to home. Huatai HT***0T, top type externally modulated optical transmitter with it's high index, high reliability and excellent cost performance, is applicable for the over-long trunk of large and middle CATV station head-end, WDM system and CFG dispersion compensation system. Product features Externally modulated technology, no laser chirp, low dispersion distortion, high extinction ratio, with excellent characteristic within *0~**2MHz, used in the over-long trunk of large and medium sized cable television head-end. Narrow line width (Typ=0.3 MHz), low noise, and DFB continuous wave laser, be propitious to reduce dispersion effect. The work bandwidth is up to *7~***0MHz. CNR ≥ *4dB and excellent CTB, CSO index. SBS: *3~*9dBm, continuous adjustable. ITU standard wavelength adjustable, used in the network upgrading and expansion of WDM system. AGC/MGC mode is optional at spot; OMI can be optimized at spot. Perfect RS**2 communicate interface. Advanced SNMP network management function. 1*1 powers supply back up. Casing temperature auto-control.
