FINISAR FTLF8519P3BNL is a 1000Base-SX SFP optical module designed for long-distance, high-reliability communication, supporting multimode fiber (MMF) transmission and suitable for industrial, data center, and harsh environments.
I. Product Description
1. Core Technical Parameters
Interface Standard: Compatible with 1000Base-SX (Gigabit Ethernet) and 2G Fibre Channel protocols, supporting 2.125 Gbps bidirectional data transmission.
Fiber and Wavelength: Utilizes 850 nm vertical cavity surface emitting laser (VCSEL) with multimode fiber (MMF), with transmission distance varying by fiber type:
50/125 μm OM2 fiber: Up to 550 meters (compliant with IEEE 802.3z standard).
62.5/125 μm OM1 fiber: Up to 300 meters.
Connector Type: Features LC duplex interface, supporting hot plugging for rapid deployment and maintenance.
Digital Diagnostics (DOM): Monitors optical power, temperature, voltage, and bias current in real-time via a 2-wire serial interface, enabling fault prediction and remote management.
Operating Temperature: -20°C to 85°C (some compatible models are marked as -40°C, but the official data sheet indicates -20°C), suitable for industrial-grade harsh environments.
Low Power Design: Consumes less than 0.5 W, with a metal casing that effectively reduces electromagnetic interference (EMI), ideal for dense deployments.
2. Protocols and Compatibility
Fully compliant with the SFP MSA multi-source agreement, compatible with mainstream switches, routers, and servers (such as Cisco, HPE, Dell, etc.).
Supports IEEE 802.3z (Gigabit Ethernet) and FC-PI-2 (Fibre Channel), meeting the requirements of both data centers and storage area networks (SANs).
II. Typical Application Scenarios
1. Industrial Automation and Smart Grids
Environmental Adaptability: The wide temperature range of -20°C to 85°C and anti-electromagnetic interference characteristics make it suitable for harsh environments such as factory workshops, substations, and oil drilling platforms.
Application Examples:
Connects industrial PLCs (programmable logic controllers), sensors, and monitoring systems to enable real-time equipment status feedback.
In smart grids, it builds stable power data transmission links through fiber optic rings, supporting remote meter reading and fault diagnosis.
2. Medical Equipment and Precision Instruments
High Reliability: Low bit error rate and long lifespan design (typical 1 million hours MTBF) meet the high-precision data transmission requirements of medical imaging equipment (such as MRI, CT) and laboratory instruments.
Application Examples:
Transmits high-speed data streams from MRI equipment to data centers for storage and analysis.
Connects hospital internal PACS (Picture Archiving and Communication System) to ensure delay-free image transmission.
3. Short-Distance Interconnection in Data Centers
Cost-Effective: Compared to single-mode solutions, multimode fiber and 850 nm optical modules are more cost-effective, suitable for short-distance connections within data centers such as row-to-row or floor-to-floor.
Application Examples:
Connects access layer switches to servers to build Gigabit Ethernet links.
In SANs, it enables high-speed interconnection between fiber channel storage devices (such as disk arrays) and hosts.
4. Security Monitoring and Transportation Hubs
Long-Distance Coverage: The 550-meter transmission distance can meet the networking requirements of surveillance cameras in large parks, airports, and high-speed railway stations, reducing the need for repeaters.
Application Examples: Multiple cameras are converged to the central control room via optical fibers to achieve,
real-time transmission and storage of video streams. In intelligent transportation systems, roadside sensors are connected to the control center to support data interaction in the Internet of Vehicles. 5. Telecommunications and Edge Computing
Multi-protocol support: Compatible with both Ethernet and Fibre Channel, suitable for hybrid network architectures in telecommunications base stations and edge server nodes.
Application cases:
In 5G base stations, it transmits fronthaul and midhaul data, supporting cloud radio access networks (C-RAN).
High-speed data backhaul between edge computing nodes and core networks to meet low-latency service requirements.
III. Selection and Deployment Recommendations
1. Fiber matching: Prioritize the use of 50/125 μm OM2 fiber to achieve a maximum transmission distance of 550 meters; if a longer distance is required, consider upgrading to OM3/OM4 multimode fiber or single-mode solutions.
2. Temperature verification: If operation in -40°C environments is required, choose compatible models (such as third-party alternative modules) and verify device compatibility.
3. Redundancy design: In critical scenarios (such as industrial control), it is recommended to adopt dual-fiber links or ring topologies to enhance system reliability.
4. Monitoring tools: Enable DOM functionality through network management systems (such as Cisco Prime, HPE OneView) to monitor module status in real time and provide early warnings of faults.
