How to convert a switch s electrical port to an optical port
An SFP (Small Form‑factor Pluggable) transceiver is a compact, hot‑swappable module that fits into a switch, router, or media converter. It converts electrical signals into optical (or copper) signals and vice versa. Our media converters provide an easy and economical solution to upgrade a copper based network to fiber optic to extend the signal reach, or to bridge copper and optical fiber cabling by converting an electrical signal to an optical signal. It allows devices with RJ45 ports to communicate over long distances via fiber, typically using SFP modules or built-in fiber ports. It is just a matter of giving you a connection to high-speed connectivity possibilities without the issues. Available as a Rackmount or Desktop, with a variety of Switch Controls, including Remote RS232, GUI. Plug the fiber optic cable into the appropriate fiber.

How to make the electrical wiring in the distribution box longer
If you have an electrical box with wiring that is too short to make electrical connections to outlets, switches or even another junction box, you will need to add 'pigtails' to the wiring in order to lengthen the wiring so you can use it. Before you reach for a clumsy extension cord, consider a more permanent fix: extending electrical wire exactly where you need it. This creates a cleaner and safer setup. A 'pigtail' is simply an extension that is added to a piece. If you're uncertain which circuit to shut off, turn off the main breaker switch to cut power to the entire house. Use your non-contact voltage detector, multimeter, or both to ensure there is no current where you're working. Colors need to be matched and safety protocols must be followed, but it is possible to splice existing wires instead of replacing the whole circuit. Once the wires are connected, fit the box back in place. * Notifiable project requiring Building Control approval if installation is located in a kitchen, bathroom or other special location.
