Product Overview of the Dell FTLX8571D3BCL-FC 10GBPS Transceiver

The Dell FTLX8571D3BCL-FC 10Gbps Ethernet 850nm SFP+SR 3.3V Transceiver is a high-speed networking device used for transmitting and receiving data between network devices. It is a small form-factor pluggable transceiver (SFP+) that supports 10 Gigabit Ethernet (GbE) over multimode fiber optic cable. The Dell FTLX8571D3BCL-FC is an SFP+ (Small Form-Factor Pluggable Plus) transceiver. This small, hot-pluggable device serves as the interface between networking equipment, enabling high-speed data transmission. The "Plus" in SFP+ indicates its enhanced capabilities over its predecessor, the SFP.

Data Transfer Speed

The "10GBPS" in the product name indicates the transceiver's impressive data transfer speed of 10 gigabits per second. This high-speed capability is particularly beneficial in scenarios where large amounts of data need to be transmitted quickly. The "10GBPS Ethernet" specification signifies that this transceiver is designed to operate in 10 Gigabit Ethernet networks. This denotes a high-speed networking standard, providing enhanced data transfer rates suitable for modern, bandwidth-intensive applications.

Wavelength and Fiber Compatibility

The transceiver operates at a wavelength of 850 nanometers (NM), making it suitable for short-distance transmissions. Additionally, it is optimized for use with multi-mode fiber (MMF), a type of optical fiber that can carry multiple light rays simultaneously. The specification "850NM" indicates the wavelength of the optical signal emitted by the transceiver. In this context, it corresponds to a wavelength of 850 nanometers. Understanding the wavelength is crucial as it determines the type of optical fiber that can be used effectively with the transceiver.

Hot Plug Compatibility

Being hot-pluggable ensures that the transceiver can be replaced or installed while the networking equipment is still running. This feature minimizes downtime during maintenance operations.

Multi-mode Fiber (MMF) Compatibility

Designed for use with multi-mode fiber, the Dell FTLX8571D3BCL-FC is optimized for short-distance data transmission. MMF is cost-effective and commonly used in environments where high bandwidth over relatively short distances is required, such as within a data center. Multi-mode fiber is a type of optical fiber that allows multiple light modes to travel along the core. This is achieved through the use of a larger core diameter, enabling multiple light signals to be transmitted simultaneously. MMF is often employed in short-distance communication scenarios within data centers and local area networks.

Data Transmission Performance

With its 10Gbps data rate, the Dell FTLX8571D3BCL-FC excels in delivering high-performance data transmission. This is especially crucial for bandwidth-intensive applications, such as high-definition video streaming or large-scale data transfers.

Reliability in Diverse Environments

The transceiver's design and specifications make it reliable in various environmental conditions. It can operate effectively in the temperature and humidity ranges typically found in data centers and networking facilities, ensuring consistent performance.

Hot Plug Functionality

The inclusion of "Hot Plug" functionality is a significant advantage in terms of convenience and flexibility. Hot plugging refers to the ability to insert or remove the transceiver from a network device without powering down the system. This feature ensures minimal disruption during maintenance or upgrades, contributing to the overall reliability of the network.

Small Form-Factor Pluggable Plus (SFP+)

The SFP+ form factor is a standardized design that allows for interchangeability between different networking devices. This flexibility is crucial in heterogeneous network environments where various equipment from different manufacturers coexist.

Compatibility with Multi-mode Fiber

The Dell FTLX8571D3BCL-FC is optimized for use with Multi-mode Fiber (MMF). Multi-mode fiber is well-suited for short-distance communication, making it an ideal choice for connections within data centers and local area networks. The compatibility with MMF enhances the transceiver's versatility, allowing it to address various networking requirements.


The Dell FTLX8571D3BCL-FC transceiver is a hot-pluggable SFP+ module that is compliant with industry standards such as the Small Form-factor Pluggable (SFP) MSA, IEEE 802.3ae 10GBASE-SR/SW, and RoHS. It has a maximum data transfer rate of 10Gbps and operates at a wavelength of 850nm. The transceiver is designed for use with multimode fiber optic cable with a maximum distance of up to 300 meters.

The transceiver supports digital diagnostic monitoring (DDM) functions such as temperature, voltage, bias current, transmit power, and receive power monitoring. These features enable network administrators to monitor the performance of the transceiver and detect potential problems before they occur.

The Dell FTLX8571D3BCL-FC transceiver is designed to operate with a single 3.3V power supply and consumes less than 1 watt of power. It has an operating temperature range of 0°C to 70°C and a storage temperature range of -40°C to 85°C.

The Dell FTLX8571D3BCL-FC transceiver works by converting electrical signals into optical signals for transmission over fiber optic cable. When a network device sends data to the transceiver, the electrical signals are converted into light pulses by a laser diode. The light pulses are then transmitted over the fiber optic cable to the receiving transceiver.

At the receiving end, the optical signals are converted back into electrical signals by a photodiode. The electrical signals are then sent to the network device for processing. The transceiver uses a standard SFP+ interface that allows it to be easily in a compatible network device.

Applications of Dell FTLX8571D3BCL-FC

The Dell FTLX8571D3BCL-FC transceiver finds applications in various networking scenarios due to its versatile features. Let's explore some common use cases.

Data Centers

In data center environments, where high-speed data transfer over short distances is crucial, the Dell FTLX8571D3BCL-FC transceiver can be employed to connect servers, storage systems, and switches.

Enterprise Networks

Large enterprises with expansive networks benefit from the transceiver's ability to provide high-speed connections between different departments or floors within office buildings.

Telecommunication Networks

Telecommunication service providers use these transceivers to establish fast and reliable connections between network nodes, facilitating the efficient flow of data in telecommunications networks.

Compatibility and Interoperability

Ensuring compatibility with existing equipment and interoperability with devices from different manufacturers is crucial in building robust and efficient networks.

Device Compatibility

The Dell FTLX8571D3BCL-FC is designed to be compatible with a wide range of networking equipment that supports the SFP+ standard. This includes switches, routers, network interface cards (NICs), and other devices.


The standardized SFP+ form factor promotes interoperability, allowing the Dell transceiver to work seamlessly with equipment from various manufacturers. However, it's always recommended to check compatibility lists provided by the equipment manufacturers to ensure smooth operation.
