XGS-PON/NG-PON2/GPON/CATV/OTDR Coexistence elements (CEx)

Advance existing PON networks with new XGS-PON

With much of the world moving to operate remotely in countless industries and businesses, the demand for reliable high-speed internet services has skyrocketed. Bottlenecks in bandwidth and speeds have sent many service providers scrambling to upgrade their network infrastructure to meet the sudden surge in service usage.

COEXISTENCE OF GPON XGSPON NGPON2 CATV RF OTDR

GPON is the access technology of passive optical network (PON) based on ITU-T G.984.x standard. It's considered as the ideal solution to FTTx (especially FTTH) with its high bandwidth, great interoperability and manageability, high efficiency, etc, which gains more and more ISPs' favor. However, with the flourishing of PON and demand for full services, people expect a higher performance of the bandwidth, service supporting capability, access network devices and so on while protecting the existing investment. Therefore, it comes to GPON's evolution to the next generation, which is 10G GPON and beyond PON standards, including XG-PON and XGS-PON, NG-PON and 50G PON.

A quick look at the latest standards from the ITU include:

XG-PON

XGS-PON

NG-PON2

50G PON

Since the uplink/downlink wavelengths are different from GPON, XGS-PON adopts the Combo solution to share ODN with GPON. The Combo optical module of XGS-PON integrates GPON optical module, XGS-PON optical module and WDM combiner. In the upstream direction, after the optical signal enters the XGS-PON Combo port, the WDM filters the GPON signal and the XGS-PON signal according to the wavelength, and then sends the signal to different channels. In the downstream direction, the signals from the GPON channel and the XGS-PON channel are multiplexed through WDM, and the mixed signal is downstream to the ONU through the ODN. Due to the different wavelengths, different types of ONUs select the required wavelength through the internal filter to receive the signal. Since XGS-PON naturally supports coexistence with XG-PON, the Combo solution of XGS-PON supports the mixed access of three types of ONUs, namely GPON, XG-PON and XGS-PON. The Combo optical module of XGS-PON is also called three Mode Combo optical module (the XG-PON Combo optical module is called a two-mode Combo optical module because it supports the mixed access of GPON and XG-PON ONUs.

Passive CEX WDM

As Fiber-to-the-home (FTTH) service providers are seeing a shift in speed & bandwidth needs away from offices, modernizing access networks have become a priority. Migrating to next generation passive optical network (NG-PON2/XGS-PON) without disruption has required coexistence elements (CEx) to bridge the gap, however options on the market are limited to cost-prohibitive proprietary solutions until now.

XGS-PON OLT/ONU SFP

LightOptics' new XGS PON OLT/ONU SFP transceivers empower service providers to leverage both PON infrastructure and existing Ethernet service platforms to effortlessly advance business services. LightOptics validates a tailored solution, including network equipment compatibility and OLT interoperability.

FIBER OPTIC REFLECTOR

Fiber optic reflector, also known as fiber Bragg grating filter, is usually installed in the front end of optical network ONU. Combined with OTDR equipment, optical link point-to-point (PTP) or point-to-multi-point (PTMP) network monitoring can be realized, and network anomalies can be reflected quickly and accurately.

New Arrivals
