Finisar's UltraSpan® Power Booster is a unique high output power EDFA designed to boost the launch power into the transmission fiber up to 26 dBm. This high output power is critical in applications requiring an improved optical signal to noise ratio (OSNR), such as high capacity 40 Gb/s, 100 Gb/s, 80 channel systems, and systems containing ultra-long spans. Packaged in a 1RU rack-mountable unit, the EDFA is network-ready including built-in software that supports SNMP communications.
The UltraSpan® Power Booster is designed to be deployed in conjunction with existing booster amplifiers. Thus, it provides relatively low gain and high output power as required for boosting the output of existing booster amplifiers from 17-20 dBm to the range of 23-26 dBm. As the product is fully compatible with existing booster amplifiers, it can easily and rapidly be integrated into any existing system design to allow the system to support OSNR critical applications requiring high launch power.
Using unique, patented, automatic power reduction mechanisms, the UltraSpan Power Booster is classified as a Class 1M laser product, although it typically provides output power of above 21 dBm. The amplifier contains two parallel fully independent eye safety mechanisms that shut down the amplifier in case of a fiber link disruption, including open connectors (PC or APC) or broken fiber, even at a distance of a few tens of kilometers from the unit.
The UltraSpan® Power Booster can optionally be provided in a high gain configuration to replace existing booster amplifiers, as well as a module for integration in a line card.
