1550nm Fiber Optic Directly ModulatedTransmitter/1550 optical direcrt modulation transmitter

The DOT55-- Series are high reliable & durable single output Fiber Optic directly modulated transmitter, which emits 1550nm Optic Carry wavelength. It employs a high performance, low noise DFB laser (JDSU, AOI, ORTEL, XT and Etc. ), build- in excellent Pre-distortion circuit, to ensure it is able to offer operator a reliable and stable transmission link, its advantage is a 1550nm wavelength, so 1550nm wavelength power can be boosted to feed fiber optic distribution network within 20km (Geographic distance ), comparing with Externally modulated transmitter, it is without the Optic Modulator and Microwave source, thus its Cost is more less than the Externally modulator transmitter. It is very suitable for using in FTTx system.
Modular design, make it easy to configure and upgrade according to different demands.
