The range of BiDi (Bidirectional) SFP (Small Form-Factor Pluggable) transceivers can vary based on the specific variant and design of the transceiver. BiDi SFP modules are commonly available in different configurations, each with its own distance capabilities. The typical range for BiDi SFP modules often falls within the short to medium-distance category.

Common BiDi SFP variants include:

1. 1310/1490 nm BiDi:

• Range: Up to 10 kilometers (km) or more for some variants.

2. 1310/1550 nm BiDi:

• Range: Up to 40 kilometers (km) or more for certain variants.

It's important to note that the range of BiDi SFP modules is influenced by factors such as the specific wavelength pairing (e.g., 1310/1490 nm or 1310/1550 nm), the optical characteristics of the fiber optic infrastructure, and the quality of the optics used in the transceiver.

When deploying BiDi SFP modules, it's crucial to match the wavelength characteristics of the transceivers with the supported specifications of the networking equipment and ensure that the fiber infrastructure meets the required standards. Additionally, refer to the datasheets and specifications provided by the transceiver manufacturer for accurate information on the range and performance of specific BiDi SFP modules.
