Description
The E2560-series EML is designed for 10 Gb/s DWDM or TDM transmission applications. The EML integrates a CW laser with an electro-absorptive modulator in the same semiconductor chip and are an extension of CyOptics’ existing E2500-series of devices. These devices can replace external modulators that are often bulkier, more expensive, and require more drive electronics than the EML. The E2560 series use a small-profile GPO ™ (SMP) connector to handle the RF signal. The package also contains a thermoelectric cooler, thermistor, rear-facet monitor photodiode, and an optical isolator.
The nominal input impedance of the E2560 version is 50Ohms. The package is qualified to the Telcordia Technologies™ TA-TSY-000468 standard.
E2560 is available in a range of ITU-T C-band wavelengths for use in DWDM systems operating at 10 Gb/s per channel. Also, E2560-series is offered as a single-channel device operating within a wavelength range of 1530 nm—1563 nm (Note: E2560S34 is at wavelength of 1550.12nm)
The devices exhibit excellent wavelength stability, supporting operation at 100 GHz channel spacing over 20 years (assuming an end-of-life aging condition of <100 pm). Typically, no external wavelength stabilization is required in systems of this type, using the CyOptics E2560 EMLs. The package also offers excellent stability of wavelength vs. case temperature, with a maximum coefficient of ±0.5 pm/C.
