Transition CETTF1012-105 10BT 10BFL 10BT ST 10BFL UTP Media Converter

Product Description

The Transition CETTF1012-105 is a legacy media converter designed to operate at 10 Mbps Ethernet speeds. It facilitates the connection between 10BT (10 Mbps over twisted pair) Ethernet devices, typically connected via an RJ-45 port, and 10BFL (10 Mbps over fiber optic) connections. This device is crucial for environments that still utilize 10 Mbps networking infrastructure or require the extension of such networks over fiber optic cabling for increased distance or electromagnetic interference immunity. This media converter allows network administrators to extend the reach of their 10 Mbps networks significantly beyond the 100-meter limitation of standard copper Ethernet cables. By converting the electrical signals from the RJ-45 port into optical signals for transmission over fiber optic cable, it enables connections over distances ranging from hundreds of meters to several kilometers, depending on the fiber type and the specific 10BFL transceiver used. The use of ST connectors for the fiber optic interface provides a bayonet-style connection, which was common for fiber optics in older installations. The 'CETT' prefix likely indicates a Copper Ethernet to Fiber Transceiver. The 'F' might denote fiber, '1012' could refer to a specific series or feature set, and '105' might indicate a revision or configuration. This device is valuable for maintaining or upgrading older network infrastructures where 10 Mbps connectivity is still required, or for specific applications that mandate fiber optic transmission at this speed.
