E2561

Data Sheet March 2003 www.DataSheet4U.com E2561-Series 10 Gb/s EML Modules for up to 80 km Transmission Description Tri Qu int The E2561-series EMLs are designed for 10 Gb/s DWDM or TDM transmission applications. The EML integrates a CW laser with an electroabsorption modulator 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 signal. 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 Technologies ™ TA-TSY-000468 standard. The EML is available in the full range of C-band ITU-T wavelengths for use in DWDM systems operating at 10 Gb/s per channel. The device exhibits excellent 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 systems 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.
