No Comments
No Commentsby www.fiber-mart.com A Passive Optical Network (PON) is a system that transmits all or most of the fiber cabling and signals to end-users. Depending on where the PON terminal is located, the system can be described as fiber-to-the-curb (FTTC), fiber-to-the-building (FTTB), or fiber-to-the-home (FTTH). The optical distribution network does not contain [ Continue reading…]
What is Fiber Optic Adapter
By Fiber-mart No Comments
No Commentsby www.fiber-mart.com What is Fiber Optic Adapter? Fiber optic adapters (also known as Fiber couplers, Fiber Adapter ) are designed to connect two optic cables together. They have a single fiber connector (simplex), dual fiber connector (duplex) or sometimes four fiber connector (quad) versions. The optical fiber adapter can be inserted [ Continue reading…]
Do you know the transceiver laser types?

What is Power-over-Ethernet (PoE)?
By Fiber-mart No Comments
No Commentsby www.fiber-mart.com PoE Definition Short for Power over Ethernet, PoE is a standard that allows Ethernet cables to simultaneously transmit data and power using a single network cable. This allows system integrators and network installers to deploy powered devices in locations that lack electrical circuitry. PoE eliminates the expense of installing additional electrical wiring which [ Continue reading…]
