The GLOBALfiber CEx LGX WDM Module (GPON / XGS-PON / RF Video / OTDR) enables simultaneous transmission of GPON, XGS-PON, RF Video overlay and OTDR monitoring on a single fiber strand—making it ideal for operators upgrading existing networks or integrating multiple services without new fiber infrastructure. Built for high performance, this module offers extremely low insertion loss, high wavelength isolation and uninterrupted operation across a wide temperature range.
Designed for FTTx, metro-access, broadband and 5G backhaul networks, this LGX form-factor module supports:
• GPON wavelengths 1290–1330 nm (upstream) / 1480–1550 nm (downstream)
• XGS-PON wavelengths 1260–1280 nm (upstream) / 1575–1580 nm (downstream)
• RF Video overlay 1540–1560 nm
• OTDR monitoring window 1600–1675 nm
With compatibility across architectures and services, the module is available in 1×4CH, 2×4CH and 4×4CH configurations, and offers SC/UPC or LC/UPC for PON ports and SC/APC or LC/APC for OTDR ports.
Key Features
• Ultra-low insertion loss: <0.9 dB (GPON), <1.1 dB (XGS-PON), <1.3 dB (RF Video / OTDR)
• Wavelength isolation > 30 dB for stable coexistence of services
• Carrier-grade temperature performance: –40 °C to +85 °C
• Available with SC/UPC or LC/UPC (PON) and SC/APC or LC/APC (OTDR) connectors
• Passive, no power required, reliable and maintenance-free
• Compact LGX plug-in module design for easy rack or cabinet install
Applications
• Fiber-to-the-home/building (FTTH / FTTB) networks
• XGS-PON upgrades preserving existing GPON services
• Networks requiring RF video overlay and OTDR monitoring
• 5G fixed wireless backhaul and fibre infrastructure
• Service provider, municipal and utility fibre networks
