Optical Module Selection for 1020km Range
In this article, ETU-LINK will deeply analyze the differences between different 10G SFP+ dual-fiber optical modules from multiple dimensions such as technical parameters, transmission distance, optical fiber type, typical applications, etc., and guide you to make the. In regional aggregation networks and metro networks, link distances often reach 10 to 20 km. Long fiber paths bring challenges such as optical power loss, higher noise levels, and strict device compatibility requirements. For many network engineers, the key question is how to maintain stable. LR (Long Reach) modules operate with a wavelength of 1310nm and require single-mode fiber to extend the effective distance to roughly 10 km. This is adequate to cover campus backbones or metropolitan network traverses. The fiber optic length, connector quality, cleanliness, and proper handling often determine whether a connection is stable or problematic.
