General Description
The FT-27 Series 1U FTTH High-Power Optical Fiber Amplifier is a high-output C-Band Er-Yb co-doped double-cladding fiber amplifier. The core components adopt high-reliability multi-mode pump lasers and double-cladding fiber, with unique APC (Automatic Power Control) and ATC (Automatic Temperature Control) circuits, ensuring high output power stability, excellent reliability, and outstanding optical path performance.
The module employs a high-stability, high-precision MPU (Microprocessor Unit) system for convenient and intelligent regulation and display. It uses proprietary technology for high-power pump leakage treatment, achieving superior specifications and more stable performance. The double-cladding erbium-ytterbium co-doped amplification technology provides 10x higher electro-optical conversion efficiency than conventional technology, resulting in lower relative cost, more compact size, and lower power consumption.
Particularly suitable for FTTH (Fiber to the Home), FTTB (Fiber to the Building), and other large split-ratio systems. The product enables multiplexing of different service wavelengths (GPON/XGPON1/OTDR and CATV) in FTTX networks, maximizing the value of the optical distribution network (ODN).
Key Features
- Optional CATV, PON system, and video combiner
