直調激光(guāng)器 10G DML Emcore or Agere 1861 Series 1310nm
發布時(shí)間: 2018-05-21 16:02
The 1861 directly-modulated laser (DML) is a cost-effective solution for 10 Gb/s digital transmission of up to 60 km using traditional intra-city SMF-28Ô single-mode fiber links. The 1310 nm wavelength eliminates the concern about dispersion control over most installed intra-city fiber plants. The package contains a high-speed DFB laser chip, thermoelectric cooler, thermistor, optical isolator, and a rear-facet monitor photodiode for external optical power control.
