Description

The E2561-series EMLs are designed for 10 Gb/s

DWDM or TDM transmission applications. The EML

integrates a CW laser with an electroabsorption modu-

lator in the same semiconductor chip. These devices

can replace external modulators that are often bulkier,

more expensive, and require more drive electronics

than the EML. The 10 Gb/s EML uses an SMP-type,

subminiature, push-on connector to handle the RF sig-

nal. The package also contains a thermoelectric cooler

(TEC), thermistor, rear-facet monitor photodiode, and

an optical isolator.

The nominal input impedance of the 10 Gb/s EML is

50 Ω. The package is qualified to the Telcordia Tech-

nologies ™ TA-TSY-000468 standard.

The EML is available in the full range of C-band

ITU-T wavelengths for use in DWDM systems operat-

ing at 10 Gb/s per channel. The device exhibits excel-

lent wavelength stability, supporting operation at

100 GHz channel spacing over 20 years (assuming an

end-of-life aging condition of <±100 pm). Typically,

external wavelength stabilization is not required in sys-

tems of this type, using TriQuint's EML products. The

package also offers excellent stability of wavelength vs.

case temperature, with a maximum coefficient of

±0.5 pm/°C.

Target Specifications

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-

lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess

of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended

periods can adversely affect device reliability.
