Finisar FCLF8522P2BTL 1000BASE-T Copper SFP Transceiver 10/100/1000Mbps RJ45 100m

Specifications are based on the manufacturer's product documentation.

Note: Host equipment must support the electrical interface and operating modes required by this copper SFP. Verify switch compatibility before ordering.

The Finisar FCLF8522P2BTL is a high-performance 1000BASE-T copper SFP transceiver designed to provide reliable Gigabit Ethernet connectivity over standard copper cabling. Supporting 10/100/1000BASE-T Ethernet speeds, this compact SFP module offers a convenient solution for connecting network switches, routers, and other compatible networking equipment through an RJ-45 interface.

With a maximum transmission distance of 100 meters over Category 5 UTP copper cable, the FCLF8522P2BTL is suitable for enterprise networks, data centers, campus networking, and Ethernet access applications.

One of its key advantages is its extended operating temperature range of -40°C to +85°C, making it suitable for networking environments that require reliable operation under demanding temperature conditions.

The Finisar FCLF8522P2BTL supports hot-pluggable installation, SFP Multi-Source Agreement (MSA) compliance, and 10/100/1000BASE-T operation in host systems with an SGMII interface.

It also supports both RX_LOS link indication and 1000BASE-X auto-negotiation, offering an advantage when compared with certain earlier FCLF8520 and FCLF8521 versions.

• Gigabit Ethernet Connectivity: Supports 10Mbps, 100Mbps, and 1000Mbps Ethernet connections.

• RJ-45 Copper Interface: Connects directly to standard Ethernet copper cabling.

• 100m Transmission Distance: Supports network connections up to 100 meters.

• Extended Temperature Range: Operates from -40°C to +85°C.

• Flexible Network Integration: Designed for compatible SFP ports with SGMII support.

• Hot-Pluggable Design: Simplifies installation and replacement.

• Reliable Link Monitoring: Supports RX_LOS link indication and auto-negotiation.

The Finisar FCLF8522P2BTL copper SFP module is suitable for various networking applications:

1. Enterprise Ethernet switching networks.

2. Gigabit Ethernet access connections.

3. Industrial networking environments.

4. Campus network infrastructure.

5. Router-to-switch copper connections.

6. Network equipment upgrades and replacements.

7. Copper-based Ethernet connections in data centers.

The Finisar FCLF8520, FCLF8521, and FCLF8522 belong to the same 1000BASE-T copper SFP product family. However, they have different link indication and auto-negotiation characteristics.

Which model should you choose?

The FCLF8522P2BTL offers both RX_LOS link indication and 1000BASE-X auto-negotiation support. It is a suitable choice when both functions are required by the host system.

The FCLF8522P2BTL is a 1000BASE-T copper SFP transceiver used to establish Ethernet connections through an RJ-45 port. It is commonly deployed in compatible switches, routers, and enterprise networking equipment.

The module supports transmission distances of up to 100 meters using Category 5 UTP copper Ethernet cable.

Yes. It supports 10BASE-T, 100BASE-TX, and 1000BASE-T Ethernet operation, subject to host system compatibility.

The main difference is the transmission medium.

• FCLF8522P2BTL uses an RJ-45 copper interface and Ethernet twisted-pair cable.

• Fiber SFP modules use optical interfaces and fiber optic cables.

• Copper SFP is convenient for short-distance Ethernet connections.

• Fiber SFP is more suitable for longer-distance connections and fiber infrastructure.

The module is designed around SFP MSA and Ethernet standards, but compatibility depends on the specific switch model, firmware, host electrical interface, and vendor qualification requirements.

Customers should confirm the switch model and required SFP specifications before purchasing.

Yes. The module features a hot-pluggable SFP design. However, follow the switch manufacturer's installation procedures to avoid network interruptions.

The supported operating case temperature range is -40°C to +85°C, making it suitable for applications requiring extended temperature performance.

Before shipment, customers can request product specification confirmation and compatibility checks.

After receiving the product, technical support can be provided for installation guidance, basic troubleshooting, and compatibility questions. Warranty terms and replacement policies should be confirmed with the seller before ordering.
