Precise Optical Monitoring With Eigenlight

Neophotonics' Eigenlight portfolio of high performance inline fiber optic power monitoring components uses patented technology that extracts a fraction of light from the fiber without breaking the continuity of the transmitted signal. The power monitors have extremely low insertion loss, low polarization dependent loss and high directivity and are used in 100G/400G systems around the world.

The products are ideal for monitoring the optical power of highly sensitive optical systems such as Optical Networks, optical networking subsystems, fiber lasers, optical sensor systems and medical laser systems. The technology deliver advanced performance through exceptional specifications. Discover a cost effective way to monitor power within an optical fiber while reducing manufacturing, supply chain and component costs.

Pure Photonics is proud to be the exclusive distribution channel in the Americas, making this superior Telecom technology available for usage in universities, labs and niche applications.

Technology

The core of the Eigenlight technology (GR-468 Telecordia Qualified) is an integrated optical tap and photodiode (see figure below) based on patented technology, which measures power within an optical fiber. 

The EigenLight optical tap technology provides a high directivity (>35dB), allowing the power in one direction within the optical fiber to be measured without the influence of the transmitted power in the opposite direction. This is ideal for FTTX applications in which the upstream power can be monitored without the influence of the downstream power (or vice versa). It also eliminates the need to monitor the reflected power due to nonlinear effects or dirty connectors.

The product is also a cost-effective solution for monitoring power within an optical fiber. By integrating the functionality of three devices (splitter, splice and photodiode, as shown in the figure above) into one advanced package, the costs of manufacturing, components, packaging waste and supply chain management are reduced.

In addition, the small footprint reduces the amount of space needed on a PCB.

S500 - Inline Optical Power Monitor The Eigenlight S500 is a low-cost and compact instrument for measuring the power of a signal being transmitted through an optical fiber. Unlike conventional power meters, this power monitor can be installed in live systems for real-time, continuous power measurement, without compromising system performance.

The EigenLight S500 is a low-cost inline optical power monitor, featuring a digital readout of the instantaneous power of a transmitted signal. The Series 500 utilizes patented optical tap technology that maintains fiber continuity, while measuring optical power. This allows for unrivalled performance among competing technology, including high directivity, low loss and low PDL. These features, in addition to the S500’s long battery life and intuitive user interface, make the Series 500 ideal for testing and monitoring the optical power of FTTX, Data Centers, Metro or Long Haul optical networks.

The S500’s fingertip controls allow for the end user to quickly select the appropriate wavelength (up to three), fast or slow sampling rate and relative or absolute power reading. The S500 comes with an advanced power saving feature that will turn the device on only when it senses optical power, ensuring a long battery life of up to three years. The Series 500 also comes with a USB interface for device power and remote control and monitoring using EigenLight’s Power Monitoring Software (sold separately). The Series 500 comes with two universal adapters, a USB cable, battery and quick start guide.
