It is specifically designed to look like the typical wide band optical node widely deployed in today’s CATV, CCTV, Multi-channel, or other sophisticated optical telecommunications network. Unique to the FOS 1000A is its ability to measure the **[Optical Modulation Index](https://www.m2optics.com/optical-modulation-index) (OMI)** of an optical carrier in percent (%), per channel, or total. This additional capability makes the FOS 1000A the most efficient and effective tool available for optimizing laser transmitter performance, saving users both significant time and money. Without this device, users spend as much as an hour performing manual calculations required to set the OMI of a single laser transmitter, while using several pieces of very expensive laboratory-grade equipment.  With the FOS 1000A, only this instrument is required and optimal OMI can be achieved in just minutes. **Optional Upgrades** - Optical Sensitivity -8dBm for low power lasers (-3dBm standard) - Additional Calibrated Wavelengths at 1490nm & 1610nm (1310/1550nm standard) - Integrated, rechargeable battery pack **Optional Accessories** - Protective carrying & storage case - Rugged patch cord set ### Related OMI Information - [**FOS 1200A Data Sheet **](https://www.m2optics.com/hubfs/Current%20Marketing%20Brochures/FOS%201200A.pdf)(1.2 GHz device)** [FOS 1000A Data Sheet ](https://www.m2optics.com/hubfs/FOS%201000A.pdf)**(1 GHz device)  ** ** **[Defining OMI](https://www.m2optics.com/defining-omi-whitepaper-download/)  ***(Technical Whitepaper)* ### ![pin-icon](https://www.m2optics.com/hubfs/M2_Optics_2021/Home/search-pin.png) **Headquarters** 5621 Departure Dr, Ste 117 Raleigh, NC 27616, USA ### ![phone-icon](https://www.m2optics.com/hubfs/M2_Optics_2021/Home/call.png) **Call Us** Phone: [1-919-342-5619](tel:1-919-342-5619) Toll Free: [866-269-2902](tel:866-269-2902) ### ![email-icon](https://www.m2optics.com/hubfs/M2_Optics_2021/Home/email.png) **Email Us** [sales@m2optics.com](mailto:sales@m2optics.com) [![M2 Optics](https://www.m2optics.com/hs-fs/hubfs/M2_Optics_2021/footer-logo.png?width=166&height=58&name=footer-logo.png "M2 Optics")](https://www.m2optics.com/) Offering customized solutions for fiber network simulation, optical time delay, and network testing applications that allow each user to specify exactly what they need.
