Migrating from GPON to XGS-PON and NG-PON2

Broadband technology and broadband markets are constantly evolving. Service providers need an optical distribution network (ODN) which not only supports today’s requirements for data, video and voice with QoS, SLA agreements and security, but also tomorrow’s requirements.

Today bandwidth scalability from GPON (2.5 Gigabit downstream/1.25 Gigabit upstream) to XGS-PON (10 Gbps upstream and downstream) and even NGPON2 (40 Gbps upstream and downstream) services are key drivers when selecting GPON OLT and ONT products – which not only future proof your investment, but provide a quick ROI.

FTTH PON Options with 10G Migration

Migrating from GPON to XGS-PON and NG-PON2

DZS’s MXK-F1421 – Modular High Capacity OLT

DZS’ MXK-F and V-series OLTs support GPON and XGS-PON (and NGPON2) in the same modular chassis and on the same ODN, providing an easy migration path to 10G services. With a complementary portfolio of ONTs, DZS provides a complete fiber to the home or business solution.
DZS’ OLTs scale from 512 subscribers in a price conscious MXK-F108 fixed interface GPON OLT up to over 32 thousand subscribers in the High Density, High Performance Modular PON/Active Ethernet OLT MXK-F1421 Chassis.
For any size network there are options which provide good price points with room to grow across the capacity and throughput range. Add either low cost or high capacity ONTs with a large combination of interface options and DZS provides network solutions to fit your network’s FTTx needs.
DZS OLT options can be installed in Central Data Centers or remote field cabinets to provide Gigabit Broadband Internet Services to rural customers. There are also a complementary set of ONUs, which transform fiber to copper for solutions where G.fast, VDSL (up to 35B) or other CO, cabinet or closet based DSLAMs will take advantage of existing phone lines in homes, apartments or businesses.

WDM1 for NG-PON2

WDM1 module is a passive optics used to support Next Generation PON (NG-PON2) with up to 40 Gigabit capacity via 4 wavelengths (4x10G per port). It combines and separates the 4 downstream (L-Band) and upstream (C-Band) wavelengths over a single fiber.

GPON and XGS-PON and NG-PON2 Coexistence Element

The Co-existence (CEx) modules are integrated into the network near the optical line terminal (OLT), enabling existing PON services to coexist with XGS-PON, NG-PON2, RF video CATV, optical time domain reflectometer (OTDR), as well as other current and future technologies. The GPON port passband, 1290-1500nm, allows for future 25G/50G services. The purpose of an upgrade port is to be able to add services not already in use, i.e. XGS-PON, CATV, NG-PON2, OTDR.

GPON Network Components - Features & Advantages
A single fiber from the OLT can deliver video, data and voice signals to hundreds of end users, and understanding a GPON Network is easier than you think. Take a closer look at how a GPON OLT device deployed in a typical GPON network delivers services to end users by way of a GPON ONT installed inside the home. LightOptics manufactured CEx WDM module is compliant with Telcordia GR-1209 GR-1221 to ensure the durability, accuracy and unlimited functionality. Each Coexistence Element (CEx) GPON/XGS-PON module we offer is guaranteed factory new and tested before shipment, regarding quality and functionality.
