Which PON variant provides enhanced security and a choice of Layer 2 protocol?

GPON gives you flexible transport and built‑in security. It uses the GPON Encapsulation Method (GEM) to carry different Layer 2 payloads over the same optical channel, so a single link can transport Ethernet frames, ATM cells, or other L2 services as needed. At the same time, GPON includes encryption of downstream data (AES-based) and robust key management, providing privacy for subscriber traffic. That combination—GEM’s support for multiple Layer 2 protocols plus built‑in security—makes it the best fit for enhanced security and L2 protocol choice.
