Finisar FCLF8521P2BTL and FCLF8522P2BTL are two 10/100/1000Base-TX SFP copper cable transceivers specifically designed for industrial and harsh environments, supporting Gigabit Ethernet connections via RJ-45 interfaces.
I. Core Product Features
1. Physical Layer Specifications
Interface Type: RJ-45, supporting Cat5/Cat5e cables, with a maximum transmission distance of 100 meters.
Data Rate: Supports 10/100/1000Mbps auto-negotiation, compliant with IEEE 802.3 standards.
Form Factor: Conforms to the SFP Multi-Source Agreement (MSA), supports hot-swapping, and is easy to deploy with plug-and-play functionality.
2. Electrical and Environmental Adaptability
Operating Temperature: -40°C to +85°C, meeting industrial-grade requirements (such as factories, transportation hubs, outdoor base stations).
Low Power Consumption: Typical power consumption is only 1.05W, supporting long-term stable operation.
Interference Resistance: The all-metal housing provides low EMI (electromagnetic interference) protection, suitable for complex electromagnetic environments.
3. Functional Differences Comparison Table
Features of FCLF8521P2BTL and FCLF8522P2BTL
Auto-negotiation: Supports 1000Base-X auto-negotiation; Supports 10/100/1000Base-TX auto-negotiation
Link status indication: None (RX_LOS pin internally grounded); Supports RX_LOS pin and LED status indicator
Configuration flexibility: Manual disabling of 1000Base-X auto-negotiation on the host side required; Accessible via I²C interface to the PHY chip, supporting custom configuration
II. Typical Application Scenarios
1. Industrial Automation and Control
Factory floor: Connects PLCs, sensors, industrial robots, etc., for real-time data transmission. For instance, in automotive manufacturing lines,
FCLF8522P2BTL's auto-negotiation function can quickly establish gigabit connections between devices, supporting industrial Ethernet protocols such as PROFINET and EtherNet/IP.
Remote monitoring: Deployed in outdoor control cabinets in wind power or photovoltaic power stations, with -40°C low-temperature adaptability,
connected to edge computing nodes via RJ-45 cables for equipment status monitoring and fault diagnosis.
2. Transportation and Infrastructure
Railway transportation: Used in video surveillance systems, Wi-Fi hotspots, and backbone networks within train carriages. For example,
FCLF8521P2BTL's low power consumption reduces the burden on on-board power supplies, while its metal casing meets vibration and electromagnetic interference requirements.
Intelligent transportation systems: In highway toll stations or intelligent traffic light systems, FCLF8522P2BTL's link status indicator can quickly locate network faults, improving maintenance efficiency.
3. Data Centers and Enterprise Networks
Short-distance interconnection: Within data centers, used for gigabit copper cable connections between servers and access layer switches, reducing costs compared to fiber optics.
For instance, the SFP ports of H3C S5500V3-SI switches can directly insert FCLF8521P2BTL to achieve a hybrid network of 24 gigabit electrical ports and 2 gigabit optical ports.
Backup link redundancy: In enterprise campus networks, serves as a backup solution for fiber optic links, automatically switching to copper cable links when fiber optic links fail, ensuring business continuity.
4. Vehicle and Mobile Devices
Intelligent vehicle systems: Supports in-vehicle Ethernet (such as ADAS sensors, in-vehicle cameras), meeting AEC-Q100 automotive-grade reliability requirements.
For example, FCLF8522P2BTL's auto-negotiation function can adapt to voltage fluctuations during vehicle startup.
Mobile base stations: In 5G small base stations, it works with FPGAs to achieve high-speed data backhaul, meeting the low-latency communication requirements between base stations and core networks.
III. Deployment Considerations
1. Protocol Configuration
For FCLF8521P2BTL, manually disable 1000Base-X auto-negotiation on the host side to avoid conflicts with 10/100Mbps modes.
For FCLF8522P2BTL, it is recommended to enable auto-negotiation to be compatible with different devices' speeds and duplex modes.
2. Cable Selection
Use Cat5e or higher-grade cables to ensure stable 1000Mbps transmission and avoid signal attenuation due to cable quality.
3. Temperature Management
In high-temperature environments, use heat sinks or ventilation designs to ensure the module temperature does not exceed the 85°C upper limit.
IV. Compatibility and Certification
Standards compliance: Compliant with RoHS, IEEE 802.3ab (1000Base-T), and SFP MSA standards.
