Data Sheet, Rev. 1 September 2001 E2500-Type 2.5 Gbits/s Electroabsorption Modulated Isolated Laser Module (EM-ILM) for Ultralong-Reach Applications Applications ■ 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 µm 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-ILM is a 1.5 µm 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 km— 1000 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 Ω. 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. 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.
