Product Description
The Finisar FCMJ-8521-3 is a Small Form-Factor Pluggable (SFP) transceiver module, also known as a mini-GBIC, designed for copper network connections. Unlike typical fiber optic transceivers, this module terminates in an RJ45 connector, allowing for integration into SFP ports for Gigabit Ethernet (1000BASE-T) connectivity over standard twisted-pair copper cabling. It supports data rates of up to 1.25 Gbps, which is standard for Gigabit Ethernet, and can achieve distances of up to 100 meters over Category 5e or Category 6 Ethernet cables. This makes it a versatile solution for extending Gigabit Ethernet connectivity in environments where fiber is not readily available or for specific copper-based network segments. The hot-pluggable nature of the FCMJ-8521-3 allows for easy installation and replacement without disrupting network operations. It is commonly used in switches, routers, and network interface cards that feature SFP slots, providing a flexible way to manage copper network connections. Its design focuses on reliable performance and efficient power usage.
