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.

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.
