- Flexible bandwidth offering from 39/39 Mbps to 1.25/1.25 Gbps per subscriber
- The affordable solution to meet various FTTx applications including FTTH, FTTC, FTTN, FTTB and FTTP
- Offer RF-over-Glass technology to provide highquality TV services
- Lower CAPEX on GEPON total solution investment, lower OPEX by employing ZyXEL’s proven centralized GEPON network manager

GEPON is the most widely deployed and matured technology with advantages like easy management, cost effectiveness and easy sharing. It is a good solution for FTTH applications. MSOs can use its RFoG (RF-over-Glass) feature as their nextgeneration cable PON to upgrade broadband bandwidth and expand customer base.

Today’s service providers are demanding larger bandwidth for subscribers to offer HDTV, MoD, VoIP and online gaming services. The options for service providers to deliver decent bandwidth are still dependent to the mixed network architecture, and the demands are being met by the deeper penetration of fiber optics in the Access Networks.

Although CATV companies now provide over 100 Mbps service with DOCIS 3.0 to compete with ILEC/CLEC, they are now considering fiber deployment for providing services such as triple-play services (voice, data and cable video; please refer to the following application figure-2). Besides, the HFC plant brings reliability/availability, powering and potentially disruptive upgrades into question; on the contrary, fiber has better reliability and PON has few plant electronics, use less power and are easier to upgrade.

On the CO (Central Office) side, video signal received from satellite to video head-end goes through amplifiers to amplify the signal. A WDM combines the wavelength of broadcasting video (1550 nm) and IP data (1490 nm) to transmit through the fiber of outside plant to home users. The WDM on the user side is to divide the wavelength to two different wavelengths (1550 nm, 1490 nm) to different transceivers. V-ONU demodulates 1550 nm signal for broadcasting video programs. GEPON-ONU demodulates 1490 nm for IP data transmission.
