Paired and used, it is easy to achieve 20KM long-distance lossless transmission

TL-MC311A-20 industrial grade and TL-MC311B-20 industrial grade are gigabit single-mode single-fiber fiber transceivers, which can convert electrical port signals and optical port signals after pairing, and carry out long-distance signal transmission through optical fiber, which are suitable for visual security, wireless networking, optical fiber access and other application scenarios.

-40°C~75°C working temperature design, no fear of extreme temperatures

TL-MC311A-20 industrial grade and TL-MC311B-20 industrial grade are designed in strict accordance with the working temperature of -40°C~75°C, selected industrial-grade devices, and natural heat dissipation mode are adopted to ensure that the equipment works stably for a long time in this temperature range and meets all kinds of harsh environments.

Industrial-grade protection design

High-standard electromagnetic anti-interference protection design, suitable for various harsh electromagnetic environments such as electric power and industrial plants.

Aluminum alloy shell and electroless nickel gold PCB board greatly improve the anti-corrosion performance of the equipment.

The housing can be protected by IP30 to reduce the impact of dust on the normal operation of the equipment.

9.6V~60VDC wide voltage input, multiple power protection

It supports two power supplies to be connected at the same time, and the power supply is redundant to ensure the uninterrupted work of the equipment.

It supports a wide voltage input of 9.6V~60VDC, and is suitable for various industrial power supplies.

Three types of power protection are provided to greatly improve the reliability of power supply to the switch.

Featured devices

The PCB board is made of electroless nickel gold plate, which has high corrosion resistance, oxidation resistance, and excellent electrical properties.

Select high-specification and long-life Japanese capacitors to greatly improve the service life of the product.

The circuit design of the highly redundant system avoids the sudden change of the external environment from affecting the normal operation of the equipment.

TP-LINK's rigorous industrial-grade production and testing process is adopted to effectively release the electrical stress of components and greatly improve the reliability of equipment.

Compact body design, metal shell, efficient heat dissipation

The size of the fuselage is only 115mm*70mm*28mm, which can be very convenient to place in a compact work cabinet, and the high thermal conductivity aluminum alloy shell has better heat dissipation effect.

DIN rail installation is easy and flexible

The TL-MC311B-20 industrial grade can be easily DIN rail mounted and wall-mounted, and the installation method can be flexibly selected according to needs, making the use of industrial-grade Ethernet switches simple and reliable.

Port interrupt alarm, real-time monitoring of port working status

TL-MC311A-20 industrial grade and TL-MC311B-20 industrial grade provide port alarm function to monitor port working status in real time. Once the port is disconnected, the alarm output of the terminal block will output an alarm signal, and the user will be alerted by the user's external alarm to the occurrence of port interruption.
