Optical Access

Delivering Ultimate Broadband
As advanced, broadband-intensive applications, like high definition video, continue to emerge, it is clear that bandwidth requirements will continue to grow. VDSL2 can extend the useful life and service capacity of copper plant, but fiber is the only technology prepared to meet future bandwidth requirements. Fiber access has moved from early adopters to mainstream communication service providers looking to gain service and operational advantages against their competition. Today, two fiber access technologies – GPON and Active Ethernet (AE) – have dominated deployments in North America. Calix offers a complete system solution for both GPON and AE.

GPON/GEPON based FTTH Solution

All fiber networks up to the subscribers are the ultimate solution of broadband connectivity because it provides fast unlimited bandwidth and enable simultaneous delivery of multiple services. FTTH, or Fiber to the Home, refers to fiber optic cable that replaces the standard copper wire of the local Telco. FTTH is desirable because it can carry high-speed broadband services integrating voice, data and video, and runs directly to the junction box at the home or building.

Gigabit Passive Optical Networks (GPON) provides a capacity boosts in both the total bandwidth and bandwidth efficiency through the use of larger, variable-length packets in PON technology. GPON is standardized in ITU-T G.984 (GPON) that permits several choices of bit rate, but the industry has converged on 2.488 Gbps of downstream bandwidth, and 1.244 Gbps of upstream bandwidth.
