Introduction to 100G BiDi optical module

  • Definition and rationale:
    The 100G BiDi optical module is a photoelectric conversion module used for high-speed data transmission, which can achieve bidirectional transmission on optical fiber. BiDi stands for Bidirectional, which uses an optical fiber to transmit both sending and receiving data signals at the same time. Compared with traditional unidirectional optical modules, 100G BiDi optical modules achieve bidirectional transmission without using additional optical fibers by using different wavelengths and optical demultiplexing technologies.

  • Fundamental:
    The basic principle of the 100G BiDi optical module is to utilize Multi-Level Wavelength Division Multiplexing (ML-WDM) technology. It uses two different wavelengths (usually 1270nm and 1330nm) to send and receive data respectively. The transmitting end encodes the data onto these two wavelengths respectively and sends them through the same optical fiber. The receiving end uses the corresponding wavelength to decode the received signal and restore it to the original data.

Bidirectional transmission requirements:
The need for high-speed data transmission in both directions is becoming more and more common in modern networks. Traditional optical modules require the use of two optical fibers for bidirectional transmission, which increases the cost and management complexity of optical fibers. The 100G BiDi optical module provides an efficient and economical solution by achieving bidirectional transmission on a single optical fiber.

The 100G BiDi optical module is a high-speed optical module that can achieve bidirectional transmission on a single optical fiber. It utilizes multi-level wavelength division multiplexing technology to transmit and receive data by using different wavelengths. As a solution to meet the needs of bidirectional high-speed data transmission, 100G BiDi optical modules can save fiber resources, simplify wiring, and are compatible with existing fiber infrastructure.

100G BiDi optical module features and advantages

  1. High-speed two-way transmission capability:
    The 100G BiDi optical module provides high-speed bidirectional data transmission capabilities, and each fiber carries the function of sending and receiving signals at the same time. This is achieved by utilizing different wavelengths for optical demultiplexing. A typical 100G BiDi optical module uses two different wavelengths (usually 1270nm and 1330nm) to send and receive data. This bidirectional transmission capability makes it possible to achieve high-speed bidirectional data communication on the same optical fiber.

Compared with traditional unidirectional optical modules, the bidirectional transmission capabilities of 100G BiDi optical modules have the following advantages:

  • Simplified wiring: Due to bidirectional transmission, it is no longer necessary to lay out two optical fibers separately for transmission and reception, thus simplifying the complexity of wiring. This reduces the number of fibers, reduces connection points and costs, and increases cabling flexibility and maintainability.
  • Improve bandwidth utilization: The 100G BiDi optical module realizes bidirectional transmission on the same optical fiber, making full use of the bandwidth resources of the optical fiber. It can meet the needs of sending and receiving data at the same time, providing higher bandwidth utilization and data transmission efficiency.

  • High-density wiring:
    100G BiDi optical modules have significant advantages in high-density wiring. Below is a discussion of the relevant advantages:

  • Reduce the number of optical fibers: By using 100G BiDi optical modules, bidirectional transmission data can be merged onto a single optical fiber, thereby reducing the number of optical fibers. Compared with traditional unidirectional optical modules, which require the use of two optical fibers for bidirectional transmission, 100G BiDi optical modules can significantly reduce the number of optical fibers used, reducing the cost and space occupied by optical fibers.

  • Space saving: Due to the reduction in the number of optical fibers, the 100G BiDi optical module takes up less space in the computer room or equipment architecture. This is especially important in space-constrained environments such as data centers, allowing for higher cabling density and better space utilization.

  • Flexibility and scalability: The high-density wiring characteristics of 100G BiDi optical modules make the network architecture more flexible and scalable. By reducing the number of optical fibers and simplifying cabling, network administrators can more flexibly plan and configure their networks to meet growing bandwidth demands.
