What is 10G BIDI SFP+ single fiber bidirectional optical module?

The main package form of BiDi single fiber optical module is SFP/SFP+/XFP.

Let's understand 10G BIDI SFP+ optical module together.

The 10G BIDI SFP+ optical module is packaged in SFP+, with a transmission rate of 10G, an LC simplex interface, and a transmission distance of up to 80 kilometers with single-mode fiber. BiDi refers to single-fiber bidirectional, which uses WDM (ie, wavelength division multiplexing) technology to send and receive different center wavelengths in both directions, thereby realizing bidirectional transmission of optical signals by one fiber.

Features and advantages of BIDI optical module:

1. The general optical module has two ports such as TX transmitting port and RX receiving port, while the BIDI optical module has only one port. The BIDI optical module can complete the transmission and reception of optical signals at the same time. Therefore, BIDI optical modules must be used in pairs.

2. The biggest advantage of the BIDI optical module is to save fiber resources and make two transmission fibers into one. BiDi optical modules reduce the cost of fiber optic cabling infrastructure and the number of ports on the fiber patch panel, and also reduce the space occupied by trays dedicated to fiber management.

Summary: BIDI single fiber optical module and dual fiber optical module use the same effect. But in the integrated wiring, BIDI optical module can not only save fiber resources, but also greatly reduce the layout cost.
