A 100m fibre optic cable is a specific length of optical fibre cable that spans 100 meters (approximately 328 feet). Fibre optic cables are used for high-speed data transmission, and their length can vary to suit different applications and requirements.

Here are some key points to consider about a 100m fibre optic cable:

1. Length: As mentioned, a 100m fibre optic cable is 100 meters long. The length of the cable is important for determining its usability in various applications.
2. Purpose: Fibre optic cables are used for a wide range of applications, including data transmission, telecommunications, internet connectivity, and networking. A 100m cable might be suitable for connecting devices within a building, between buildings , or for other medium-distance applications.
3. Fibre Type: Fibre optic cables come in different types, such as single-mode and multi-mode. The choice of fibre type depends on the specific application and the required transmission distance and bandwidth.
4. Connectors: Fibre optic cables are typically terminated with connectors on each end to facilitate easy connection to networking equipment, switches, routers, or other devices. Common connector types include SC, LC, and ST, among others.
5. Data Rate: The data rate or bandwidth that a 100m fibre optic cable can support depends on the type of fibre and the equipment it's connected to. For example, single-mode fibre can support higher data rates and longer distances compared to multi-mode fibre.
6. Signal Loss: Over a distance of 100 metres, signal loss in a fibre optic cable is generally minimal, especially if it's single-mode fibre. However, it's important to consider signal attenuation when designing a fibre optic network.
7. Jacket Type: Fibre optic cables have protective jackets made of materials like PVC, plenum, or LSZH (Low Smoke Zero Halogen), depending on where they will be installed. The choice of jacket type depends on safety and environmental considerations.
