About This Part
The Finisar FCM-8520-3 is a high-performance Gigabit Interface Converter (GBIC) transceiver, specifically a GBIC-T variant, engineered for robust copper connectivity in enterprise and data center networks. This hot-pluggable module adheres to the GBIC form factor, facilitating seamless integration into compatible network equipment. Its primary function is to enable Gigabit Ethernet (1000BASE-T) communication over standard Category 5e/6 unshielded twisted-pair (UTP) copper cabling. The Part Number FCM-8520-3 supports a full-duplex data rate of 1.25 Gbps, compliant with the IEEE 802.3ab standard, ensuring reliable and high-speed data transmission. Designed for short-reach applications, it provides connectivity up to 100 meters, making it ideal for interconnecting servers, switches, and other network devices within racks or across adjacent rooms. The module features a standard RJ-45 connector for easy deployment and robust electrical signaling, ensuring stable performance in demanding B2B environments. This Finisar GBIC-T transceiver is widely deployed in various network infrastructures where Gigabit Ethernet over copper is required. It is commonly installed in core, distribution, and access layer switches, routers, and network interface cards (NICs) within data centers, enterprise campuses, and telecom central offices. The FCM-8520-3 supports a broad range of network platforms from leading vendors that utilize GBIC slots, providing a cost-effective solution for extending or upgrading existing copper-based network segments. Telecom operators and large enterprises leverage this module to connect legacy equipment, integrate new devices into existing copper backbones, or establish short-distance links where fiber optic cabling is not practical or necessary. It effectively solves the problem of achieving high-speed copper connectivity over standard infrastructure, often replacing older, lower-speed copper modules or enabling the upgrade of 10/100 Mbps links to full Gigabit speeds without extensive re-cabling.
