Description

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.
