Huawei Optical Modules are designed to provide high speed data transmission over long distances with minimal signal degradation. The specific model mentioned, "1.25G TX 1490nm RX 1310nm 10km SM BIDI SFP," has the following key specifications and characteristics:

Basic Information:

1. Part Number: 34060475

2. Type: SFP (Small Form factor Pluggable)

3. Data Rate: 1.25 Gbps

4. Wavelength: TX (Transmit)   1490nm, RX (Receive)   1310nm

5. Distance: 10 km

6. Fiber Type: Single Mode (SM)

7. Interface: BIDI (Bidirectional), meaning it can transmit and receive signals on the same fiber strand, doubling the capacity of the fiber link.

8. Compliance: Typically, these modules comply with industry standards such as SFF 8472, GBIC, and possibly others depending on the specific model.

Transmitter Receiver Characteristics:

1. Transmitter (TX):

  Wavelength: 1490nm

  Output Power: This is a critical parameter and can vary, but it is typically in the range of  3 to +3 dBm.

  Modulation: Often uses NRZ (Non Return to Zero) or similar encoding schemes.

2. Receiver (RX):

  Wavelength: 1310nm

  Sensitivity: This is the minimum input power at which the receiver can correctly interpret the signal, often specified as  25 dBm or better.

  Optical Filter: May include a wavelength division multiplexing (WDM) filter to separate the transmit and receive wavelengths.

3. Optical Budget: This is the difference between the transmitter output power and the receiver sensitivity, which gives an indication of the margin available for signal loss over the fiber.

4. Connector Type: LC (Lucent Connector) is common for SFP modules.

5. Operating Temperature: Typically, these modules are designed to operate in a range from 0°C to 70°C.

6. Storage Temperature: Often specified as  40°C to 85°C.

7. Power Consumption: SFP modules usually consume low power, often less than 2 watts.

8. Dimensions: SFP modules are standardized with dimensions of approximately 9.3mm x 30mm x 75mm.

9. Environmental: They are designed to be resistant to various environmental conditions such as humidity, vibration, and shock.

10. Safety and Compliance: They should meet safety standards such as CE, FCC, and RoHS.

When using these modules, it's important to ensure compatibility with the network equipment they will be installed in. Compatibility can depend on the specific model of the equipment and the firmware or software version. Always refer to the equipment manufacturer's guidelines for compatibility and installation procedures.
