| PGE 608 17 EDFA Gain Block for DWDM Applications Key Features * Operating wavelength window: 1543-1558 nm * Gain flatness < 0.5dB * Low noise figure, typ. <5.5 dB * +13 dBm output power * Input and output monitor diodes * Operation temperature range: -5 C to 70 C * Multisourced footprint * Small size (120x80x15 mm) Applications * Booster amplifier in single-channel or DWDM networks Description The DWDM gain block is intended to be used as a booster amplifier in WDM/ DWDM networks. The gain block has input and output power monitoring. The input and output ports have isolators to attenuate spurious reflections in the system. External electronic circutry is needed for biasing the pump laser and for controlling the pump laser temperature. Heat sink is provided via the bottom surface. 1 PGE 608 17 Optical input signal Input power monitor Optical gain Output power monitor Optical output signal 28 pin electrical interface Optical output power monitor Figure 1.

This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. 3 PGE 608 17 Handling Precautions This device may be damaged as a result of electrostatic discharge (ESD). Take proper precautions during both handling and testing. This typically includes grounded wrist wraps, workbenches and floor mats in ESD controlled areas. Semiconductor devices may be damaged by current surges, use appropriate transient protection. Quality Assurance Ericsson Microelectronics commitment to quality has been proven through a decade of semiconductor device production and has been confirmed to ISO 9001. Opto product qualification is made according to the intention of applicable Telcordia standards.
