Caution!
Risk of eye injury. When inspecting a connector, ensure that light sources are off. The light
source in fiber optic cables may cause eye injury. SX and LX fiber connections use invisible IR
light.
15.4.1 Parts included
The box contains the following parts:
Quantity Component
1 SFP fiber transceiver
No tools or Ethernet cables are provided with the device.
15.4.2 Application
Fiber transceivers are especially beneficial in environments where high levels of
electromagnetic interference (EMI) is a common phenomenon, like industrial plants. This
interference can cause data corruption over copper‑based Ethernet links. However, data
transmitted over fiber optic cable is completely immune to this type of noise, ensuring optimal
data transmission across the plant floor.
For short distance transmissions multi‑mode fibers can be used using light with a wavelength
of 850nm, while single‑mode fibers typically support distances up to 10km, using light with a
wavelength of 1310nm. Some third party dedicated SFP fiber transceivers can even cover
