COMMSCOPE CO-115592.3-EN Coexistence Singlemode Devices Instruction

Manual

Solutions overview

Passive Optical Network (PON) standards have been designed to enable two or more PON systems to co-exist over the same Optical Distribution Network (ODN) thanks to the use of separate wavelengths for both upstream and downstream communications. That allows increased data speed and the delivery of additional services without replacing any of the existing passive fiber network infrastructure, while keeping previous services active.
CommScope’s coexistence elements support your migration to next-generation PON services while controlling costs.
Our portfolio of coexistence modules are designed to integrate into the network using fiber panels installed near the optical line terminal (OLT) or inside the optical distribution frame (ODF). They enable different generations of PON technologies such as GPON,
XGS-PON, NG-PON2, 25GS MSA, 50GPON to coexist, potentially using different optical split ratio. In addition, some modules have separate ports to enable RF video, optical time domain reflectometry (OTDR), or WDM overlays. Many modules feature an upgrade port enabling the addition of future services over unused wavelengths.
CommScope’s CEx elements are available in 2 housing styles, LGX and NG4, offering solutions for both inside plant (ISP) and outside plant (OSP) deployment.

| GR-1209/GR-1221 and GR-63

Our LGX solutions meet Outside plant (OSP) requirements of -40°C to +70°C operating temperature environments, and are tested to IEC 61300-2-1, -9, -21, -22, -26 and GR-1209/GR-1221 requirements.
Our NG4 solutions are available with LC/APC connectors, meet inside plant (ISP) requirements of -10°C to +65°C operating temperature environments, and are tested to GR-1209/GR-1221 and GR-63 requirements.
