SONET/SDH extended-reach applications . High-capacity DWDM system applications . High-speed data communications . Digitized video Description The E2500 EM-ILM, the newest generation of the awardwinning 266-Type EM-ILM, features an integrated modulator and laser chip, and provides a compact, cost-effective solution for extended-reach transmissions . Features . Integrated electroabsorptive modulator . 1 .5 pm wavelength . Characterized for 2.5 Gbits/s operation . Very low dispersion penalty over 600 km . Low modulation voltage . Temperature stabilized . Wavelengths selectable to ITU-T standards . Ultrastable wavelength aging performance for DWDM systems The E2500-Type EM-I LM is a 1 .5 pm laser with an integrated electroabsorptive modulator packaged in an industry-standard, 14-pin butterfly package . The device has been designed to be used in 2.5 Gbits/s extended-reach applications where the distances between regenerators is in the range of 150 km1000 km . To boost the transmitter power high enough to reach the receiver, the device typically is coupled with an erbium-doped fiber amplifier (EDFA) such as Agere Systems Inc.'s 1724 EDFA. The standard product is specified for use up to 360 km (E2505 Series) and 600 km (E2502 Series) . The E2500 EM-ILM can replace external modulators in many applications . The nominal input impedance for the modulator is 50 52. By integrating the modulator with the laser chip, the device offers a compact, cost-effective solution for extended-reach transmission applications . It can also be specified for WDM applications where wavelength selection is required. Agere is providing devices compatible with the ITU-T wavelength standards . AdLib OCR Evaluation E2500-Type 2 .5 Gbits/s Electroabsorption Modulated Isolated Laser Module (EM-ILM) Data Sheet, Rev. 1 September 2001 Description (continued) Pin Information The package also contains a thermoelectric cooler, thermistor, back-facet monitor, and an optical isolator. Table 1 . Pin Assignments This device exhibits excellent wavelength stability, supporting operation at 100 Gbits/s channel spacing, assuming an end-of-life condition of < 100 pm over 20 years for wavelength aging, with very low FIT rates . Wavelength stabilization schemes are not required in DWDM systems of this type, using Agere's E2500Type EM-ILM . The E2500-Type EM-ILM is qualified for DWDM applications to Bellcore TA-TSY-000468 .
