Product Description
The Transition Networks SBFTF1011-105-NA is a Fast Ethernet media converter that serves as a vital link between copper and fiber optic network segments. It allows a standard 10/100Base-TX Ethernet connection using an RJ45 connector to be extended over a 100Base-FX fiber optic link. This capability is essential for overcoming the distance limitations of copper cabling, enabling network connectivity across buildings, campuses, or other geographically dispersed locations. This model utilizes an ST fiber connector, a bayonet-style connector commonly used with multimode fiber. It supports 100Base-FX transmission, typically over multimode fiber for distances up to 2 kilometers (approximately 1.2 miles) at a wavelength of 1310nm. The copper port supports auto-negotiation for speed (10 or 100 Mbps) and duplex mode (half or full), ensuring compatibility with a wide range of network devices. The fiber optic port operates in full-duplex mode. With its ability to convert between copper and fiber, the SBFTF1011-105-NA provides a cost-effective solution for network expansion and upgrades. It is particularly useful in environments where fiber optic cabling is already in place or is required for increased bandwidth, immunity to electromagnetic interference, or longer transmission distances. Status LEDs on the unit provide clear visual feedback on link status, activity, and power, simplifying network management and troubleshooting.
