In modern all-optical local area network (POL) architectures, the Optical Line Terminal (OLT), as the central device connecting the core network and user-side Optical Network Units (ONUs), directly determines the service continuity of the entire network.

ChengGe's NFV product line's BRAS solution addresses this need by building a secure, intelligent, and reliable access defense for small and medium-sized ISPs through an efficient, flexible, and scalable authentication mechanism.

Using CAPTCHA mechanisms (such as Google reCAPTCHA) to distinguish between human and machine operations can prevent legitimate users from being mistakenly locked out due to incorrect operations.

Amid the deepening informatization of education, campus networks are evolving from traditional "internet access" to high-speed, intelligent, converged, and reliable all-optical networks.

In today's era of sweeping digitalization, scenarios like campuses, hotels, and enterprise LANs are increasingly in need of high-speed, stable, and efficient networks.

FEC technology works together with other functional modules of the OLT to further enhance anti-interference capabilities.
