A 16-Port × 22 dBm WDM EDFA (Erbium-Doped Fiber Amplifier) is a high-power optical amplifier designed for CATV and PON systems, delivering stable 22 dBm output per port with wavelength-division multiplexing (WDM) capability. It is widely used in FTTH/FTTB deployments to combine and amplify signals for large-scale distribution.
🔑 Key Features
High Output Power: Each of the 16 ports provides 22 dBm output, ensuring strong signal distribution across wide networks.
WDM Integration: Supports combining CATV (1550 nm) with PON wavelengths (1310/1490 nm for XPON, 1270/1577 nm for 10G PON).
Stable Performance: Built-in APC (Automatic Power Control) and ATC (Automatic Temperature Control) circuits maintain consistent output.
Network Compatibility: Compatible with OLT/ONU systems from major vendors like Huawei, ZTE, and FiberHome.
Redundancy & Reliability: Dual power supply options (AC 90–265 V or DC -72 to -36 V) with hot-swappable modules.
Management Interfaces: Supports SNMP and web-based monitoring for easy integration into network management systems.
