Optical Fiber
Product Code : SCL-PL-12410
Optical Fiber (SKU SCL-PL-12410) is a thin, flexible 1 mm plastic strand that carries light along its length, the same principle that lets optical fibres transmit data as pulses of light. It can be used to demonstrate total internal reflection and to introduce fibre-optic communication in Class 12 and college optics. Science Lab Supplies manufactures it at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and schools, colleges, tender contractors and distributors can order it directly.
Specifications
The fibre is a round strand of plastic, 1 mm in diameter, white in colour and water resistant. It is thin and flexible, so it can be bent along a path while light entering one end still emerges at the other, showing how light is guided by total internal reflection.

Applications and Experiments for the Optical Fiber
Shining a torch, LED or laser into one end and watching the light emerge from the other, even when the fibre is curved, shows total internal reflection in action. The same demonstration introduces how optical fibres carry data as light pulses in communication networks and in sensing.
- Class 12 physics (NCERT ray optics): total internal reflection and optical fibres.
- B.Sc. and diploma electronics: introduction to fibre-optic communication.
- STEM activities: light-guide models and simple signalling projects.
Standard Scope of Supply
The Optical Fiber is supplied as a round, white 1 mm plastic strand as described above, and the length per unit is confirmed on the quotation. A light source such as a torch, LED or laser pointer is not included and can be added to the same quotation.
Packing, MOQ and Lead Time
One fibre or a quantity for a whole class can be quoted, and Science Lab Supplies will state the packing, delivery time and price on each quotation. Ray boxes, refraction sets and other optics lab equipment for schools can be quoted with the fibre to complete a light-guide lesson.
As a holder of an Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Ghana, Ethiopia, Tanzania, Uganda, the UAE and Saudi Arabia. For details write through the contact page, collect items in the enquiry cart, or visit the lab tender page for tender purchases.
Frequently Asked Questions
How does an optical fibre carry light?
Light entering one end strikes the inner surface at a large angle and is totally internally reflected again and again, so it travels along the strand and leaves at the far end, even around gentle bends.
What are the specifications of this fibre?
It is a round plastic fibre, 1 mm in diameter, white in colour, thin, flexible and water resistant. The length supplied per unit is stated on the quotation.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer, not a trading company. It produces this item at its factory in Saha, Ambala, Haryana, and buyers receive quotations from that same factory.
Which light source should be used with the fibre?
A torch, LED or low-power laser pointer can be used. With a laser, never look into the beam or the fibre end, and keep the demonstration under teacher supervision.
