I am trying to find a solid core single mode optical fiber with a core refractive index well above or below 1.5 (e.G. Say greater than about 1.7 or less than about 1.3) for a special relativity experiment. Also it would be nice to have attenuation of <3 db/km.
Please don't contact me if you don't know of such a product.

Optical Fiber Cable
We are looking for information on below questions:
• what are drop cables? What is the difference between drop and indoor cables?
• what is the difference between normal drop cables and hardened connectors?
• in case of hardened connectors, why is the cost per foot not similar, ? Is it because the connector is of fixed cost plus cost for the length of the cables?
• how does multi-mode with less fiber count compare to single mode with high fiber count in terms of application, pros and cons and cost?
• what's the use of armored cables apart from making cables detectable? Are there toned outdoor cables with single metal wire for detecting purposes like in the case of drop cables?
• what is the need of fibres to be detectable (armored/toned) if they're laid in building duct systems?
• why do drop optical fiber cables come in standard lengths?
• how are optical cables connected? Can connectors be put on the field or they have to put in the factory at predetermined points?
• what are the cost and time factors involved in connecting them in factory and on field. If can be put on field, what's the importance of fnap?
• can two drop cables with connectors be connected on field?
• can hardened drop cables be connected to normal drop cables on field?
• can higher fiber count cables be split into separate lower count fibers? Is that cost effective? Where can those splitted cables be used?
• how frequently do cables need to be replaced? Are their in regulatory standards on the frequency?
