The modulation speed and transmission distance strongly depends on the spectral line-width of the laser. The laser properties themselves are not changed by the process of modulation, as they are in a DML. We, Opterna Technologies Pvt. EMLs are advantageous in applications with higher speeds and longer distance transmission, compared to a DML, because of its smaller chromatic dispersion. The new module, which comprises an electro-absorption modulator laser EML and a transmitter optical sub-assembly TOSA , reduces fluctuations in optical wavelengths for dense wavelength-division multiplexing DWDM. C-band, with GHz spacing.

On 1 February, Tokyo-based Mitsubishi Electric Corp will start shipping the new Model FUREA 10Gbps optical transmitter for high-speed, large-volume data transmission between base-stations and central offices in radio access networks within mobile telecommunication systems.
In most cases, permission will ekl granted, if the magazine and publisher are acknowledged. In LTE and LTE-Advanced fourth-generation 4G mobile systems, DWDM has attracted attention as a means of reducing the power consumption of optical transmitter modules that transmit data between base-stations and central offices.

The modulation speed and transmission distance strongly depends on the spectral wml of the laser. Compared to a DML, an EML has smaller chromatic dispersion with a stable wavelength under high-speed operation, because the injection current input signal to the laser section is not modulated and therefore does not change.
We, Opterna Technologies Pvt. EMLs are advantageous in applications with higher speeds and longer distance transmission, compared to a DML, because of its smaller chromatic dispersion. A narrower line-width is required for higher modulation speed data rate and longer distance.
