Basic Information:

The Huawei GPON ONU SFP Module is a high performance optical networking device designed for use in Gigabit Passive Optical Network (GPON) systems. It is specifically engineered to meet the demands of next generation broadband access networks. This SFP module is identified by the model number HPSP2120.

Transmitter Receiver Characteristics:

1. Wavelength:

  TX (Transmit): 1310nm

  RX (Receive): 1490nm

These wavelengths are standard for GPON systems, with 1310nm typically used for downstream transmission and 1490nm for upstream.

2. Data Rates:

  TX: 1.25Gbps

  RX: 2.5Gbps

The transmit data rate is 1.25Gbps, which is the standard rate for GPON downstream traffic. The receive data rate is 2.5Gbps, indicating that the module is capable of handling higher upstream data rates, which can be beneficial for applications requiring faster upload speeds.

3. Interface Type:

  SC (Square Connector)

The SC connector is a push pull locking mechanism type of optical fiber connector used to achieve a robust connection.

4. Fiber Type:

  SM (Single Mode)

The module uses single mode fiber, which is suitable for long distance transmission and provides better performance in terms of signal integrity over distance compared to multi mode fiber.

5. Distance:

  20km

The module is designed to support transmission distances of up to 20 kilometers, making it ideal for connecting remote locations or extending the reach of a GPON network.

6. Other Specifications:

  The module likely supports Hot Pluggable Small Form factor Pluggable (SFP) standards, allowing for easy installation and replacement without the need to power down the system.

  It may also feature digital diagnostics functions that provide real time information about the module's performance, including temperature, voltage, and received optical power levels.

Summary:

The Huawei GPON ONU SFP Module HPSP2120 is a versatile and high performing component designed for GPON networks. It offers a combination of long distance transmission capabilities, high data rates, and compatibility with standard single mode fiber and SC connectors. This makes it a reliable choice for enhancing the performance and reach of broadband access networks.
