GP-7500 OLT XGS-PON
CXR GP7500-16 OLT is an XG(S)-PON and GPON multi-service OLT.
It supports various networking modes such as FTTH, FTTO, FTTD, and POL, enabling comprehensive access for both residential and enterprise users. This OLT facilitates full-service integration over a single optical fiber network, simplifying the network architecture and reducing OPEX.
Standard Compliance
Adheres to ITU-T G.984/G.987/G.9807/G.988, 10-Gigabit-capable symmetric passive optical network (XGS-PON), communications industry standard "Access Network Technical Requirements—Gigabit Passive Optical Network (GPON)," and GPON equipment technical requirements CTC 2.0.
Interoperability
Excellent interoperability with automatic discovery and compatibility with third-party ONT devices.
Hardware Redundancy
Dual hot- swappable power supplies with redundancy design ensure stable operation.
Green and Eco-Friendly
Low power consumption reduces operational costs.
Trunk Fiber Protection
Supports automatic link protection when fiber faults occur.
Power Characteristics
Supports dual AC, dual DC, and mixed AC/ DC power supply configurations; adopts a modular design, is hot- swappable, and meets EMC level 3 standards; has superior environmental adaptability compared to similar products.
