There are numerous options for extending hybrid fiber/coaxial (HFC) networks with more fiber. The different approaches
give cable operators a choice of how to provide more customers more services, and how to conduct the migration to IP services.
Passive optical network (PON) technology was initially adopted most widely by telephone companies. PON is evolving to increase the bandwidth and the number of transport protocols supported (with Ethernet increasing in popularity). Originally, PON was
single-wavelength; the trend is toward using multiple wavelengths.
There are PON variations being developed aimed at attracting cable operators. Some support DOCSIS transport, and those
versions typically contain a “D” in the acronym. Another variation supports an optical bridge between equipment that continues to
operate in the radio frequency domain; variations include RF-PON and RF over glass (RFoG).
Many companies can provide multiple variations of PON technology. Others, such as Clearfield and Corning, provide basic network elements any operator would need to deploy with an extension of optical delivery in the last mile.

Calix is the largest supplier of PON solutions to cable operators.
Since introducing the industry’s first GPON ONT with an integrated RFoG micronode, more than 30 CableLabs and NCTC members have deployed the Calix 725 ONT for business and residential applications. The recently announced 725GX ONT continues
this innovation by adding full 1 GHz capability and adding 1610
nm return path, in addition to the previously available 1590 nm
version. The 725GX ONT features a full GE of Ethernet, two voice
ports and a +18 dBmV RF output. Calix GPON is an ideal solution for cable operators interested in serving businesses and cell
site backhaul due to its ability to support 10/100/1000 Ethernet,
as well as TDM-based T1 services. Calix offers the widest portfolio
of ONTs in the industry, including versions for small and large businesses, MDUs and single-family residences.

Corning Cable Systems’ AFAN System establishes a universal all-fiber access network foundation for state-of-the-art commercial and residential services. The solution
retains a traditional MSO feel, yet brings an innovative approach to the network of
the future.
• As MSO business models evolve, their networks must support new technologies and be adaptable to future capacity enhancements. New electronics now make it possible for MSOs to migrate to an all-fiber platform.
• MSOs will benefit from the AFAN System with lower maintenance costs by eliminating or minimizing network power, battery maintenance, RF leakage testing and troubleshooting, and amplifier balancing.
• Combined with advancements in electronics, Corning’s AFAN System offers the long-term bandwidth potential MSOs need and
makes the logical progression of optical fiber to the premise easier than ever for MSOs to leverage.
Development of Corning’s AFAN System has been influenced by nearly a decade of fiber-to-the-premise deployments, and Corning continues to share that experience with you through high-quality products, design and deployment assistance, training, and the
tools you need for success.
