The Huawei BiDi Transceiver, QSFP28, 1331nm TX, 1271nm RX, 50G,  4.5dBm, 4.2dBm,  8.9dBm, LC, 10km, Part Number: 02312EVV, is a high performance optical transceiver module designed for use in high speed data communication networks. Here's a breakdown of its key specifications and characteristics:

Basic Information:

  Part Number: 02312EVV

  Brand: Huawei

  Transceiver Type: QSFP28 (Quad Small Form factor Pluggable)

  Wavelength: 1331nm for TX (Transmit) and 1271nm for RX (Receive)

  Data Rate: 50Gbps (Gigabits per second)

  Distance: Designed for 10km (kilometers) transmission

Transmitter Receiver Characteristics:

  TX Output Power:  4.5dBm (decibels relative to a milliwatt) at 1331nm

  RX Sensitivity: 4.2dBm at 1271nm

  Optical Power Budget:  8.9dBm

  Connector Type: LC (Lucent Connector)

Additional Details:

  BiDi (Bidirectional): The transceiver is capable of transmitting and receiving signals over a single fiber strand, which can help save on fiber deployment costs and simplify network architecture.

  Form Factor: QSFP28 is a compact form factor that supports high density configurations, making it suitable for data centers and high speed networking applications.

  Wavelength: The specific wavelengths of 1331nm and 1271nm are chosen to optimize performance and minimize interference in the optical spectrum.

  Optical Power Budget: This is a measure of the margin available for signal loss before the receiver can no longer reliably detect the signal. A higher budget indicates better performance in the presence of signal degradation.

This transceiver is designed to meet the demands of modern data centers and telecommunications networks that require high speed, reliable, and efficient data transmission over long distances. Its bidirectional capability and high data rate make it an excellent choice for applications where both space and bandwidth are at a premium.
