This article introduces single-fiber optical modules and dual-fiber optical modules commonly used in optical communications. Single-fiber optical modules use only one optical fiber for bidirectional transmission, which has space advantages. The dual-fiber optical module uses two optical fibers for signal transmission, which has higher stability and reliability. Choose the appropriate optical module type according to the application scenario and needs.
With the continuous development of optical communication technology, optical modules are increasingly used in various communication equipment. Among them, single fiber transceiver modules and dual-fiber optical modules are two common types of optical modules. This article will introduce single-fiber optical modules and dual-fiber optical modules.
1. Single fiber optical module
Single-fiber optical module, also called BIDI single-fiber bidirectional optical module, refers to an optical BIDI module that uses only one optical fiber to transmit data. This optical module uses WDM (wavelength division multiplexing) bidirectional transmission technology to achieve simultaneous bidirectional transmission in the optical channel on the same light. Single-fiber optical modules save more space in fiber cabling. Since the single-fiber optical module adopts bidirectional transmission technology, the same jump fiber can be used for bidirectional communication, which can effectively reduce the number of optical fibers used. This can not only save the investment cost of optical fiber, but also reduce the occupation of wiring space and increase the density of network equipment. Single-fiber optical modules must be used in pairs.
2. Dual fiber optical module
Dual-fiber optical module refers to an optical module that uses two optical fibers to transmit data. Dual-fiber optical modules use two optical fibers to transmit signals, one for sending optical signals and the other for receiving optical signals.
3. Comparison between single-fiber optical module and dual-fiber optical module
Single-fiber optical modules and dual-fiber optical modules are two common types of optical modules. They all play an important role in optical fiber communications. The single-fiber optical module uses WDM technology to achieve bidirectional transmission in a single optical fiber, improving fiber utilization. The dual-fiber optical module realizes bidirectional transmission of optical signals and improves the stability and reliability of the network. In actual use, the appropriate optical module type should always be selected based on the application scenario and needs.
