Basic Information:

The Huawei QSFP 40G SDLC PAM is a high performance transceiver module designed for data communication applications. It operates at 40Gbps and is based on the Serial Digital to Level Converter (SDLC) technology, which is a method of encoding data for transmission over fiber optic cables. The module is compatible with the QSFP+ form factor, which is a popular industry standard for high density, high speed optical transceivers.

Key Specifications:

  Data Rate: 40Gbps

  Interface Type: QSFP+

  Wavelength: 850nm

  Encoding: PAM4 (4 Level Pulse Amplitude Modulation)

  Connector Type: LC (Lucent Connector)

  Transmission Distance: 0.1km on OM3 multimode fiber and 0.15km on OM4 multimode fiber

  Part Number: 02311PUU

Transmitter Receiver Characteristics:

The transmitter section of the module is responsible for converting electrical signals into optical signals for transmission over fiber. It uses 4 Level Pulse Amplitude Modulation (PAM4), which allows for higher data rates by encoding more bits per symbol. The receiver section, on the other hand, converts the incoming optical signals back into electrical signals for processing by the host device.

  Transmitter Power Output: The transmitter section provides a stable and consistent power output at 850nm wavelength, which is optimal for short range, high speed data transmission.

  Receiver Sensitivity: The receiver is designed to be sensitive enough to accurately detect the incoming signals over the specified distances on OM3 and OM4 multimode fibers.

  Signal Integrity: The module ensures high signal integrity with minimal distortion or interference, which is crucial for maintaining data integrity over the fiber link.

  Temperature Range: The module is designed to operate within a wide temperature range to ensure reliable performance in various environmental conditions.

Applications:

This transceiver module is typically used in data centers, high performance computing environments, and telecommunications infrastructure where high speed data transmission is required. Its compatibility with OM3 and OM4 multimode fibers makes it suitable for both new installations and upgrades in existing networks.

Conclusion:

The Huawei QSFP 40G SDLC PAM is a robust and efficient solution for high speed data transmission in modern networking environments. Its use of PAM4 encoding and compatibility with QSFP+ form factor make it a versatile choice for a wide range of applications. With its specified performance characteristics, it ensures reliable and high quality data transmission over short distances on multimode fiber.
