Features
Multi-wavelength multiplexing and demultiplexing:
Supports multiplexing and demultiplexing of 4 regular wavelength channels, typically in the wavelength range of 1471 nm to 1611 nm, with a channel spacing of 20 nm.
The additional ‘+1’ channel is typically used for monitoring or managing signals (e.g. 1310 nm or 1550 nm).
Integrated monitoring channel (+1):
The ‘+1’ channel is dedicated to the transmission of monitoring signals for real-time monitoring and management of network performance.
The monitoring channel can transmit network status information, fault alarm signals or remote control commands.
Low insertion loss and high isolation:
Low insertion loss (typically <1.5 dB) ensures efficient signal transmission.
High channel isolation (>30 dB) reduces crosstalk between channels and ensures signal purity.
Compact design:
Adopts a compact package, suitable for space-constrained application scenarios.
High Reliability:
Suitable for a wide temperature range (typically 0°C to 70°C), adapting to various working environments.
Why ‘+1’？
Network monitoring and management:
The ‘+1’ channel is dedicated to the transmission of monitoring signals, enabling real-time monitoring and management of network status.
It can quickly detect network faults, signal degradation and other problems to improve network reliability.
Remote control and configuration:
The ‘+1’ channel enables remote configuration and management of network devices, reducing manual maintenance costs.
Enhanced Network Flexibility:
The additional monitoring channel provides more flexibility and scalability for the network, suitable for complex network environments.
Improved O&M efficiency:
The monitoring channel transmits network performance data in real time, helping operations and maintenance staff to respond and handle problems quickly.
Applications
Fibre optic communication networks:
Used in metropolitan area networks (MANs) and access networks to enhance fibre bandwidth utilisation.
Supports multi-wavelength signal transmission in 5G pre-transmission and mid-transmission networks.
Data Centre:
Supports high-density and high-bandwidth data exchange requirements.
Used for optical interconnection within data centres to improve data transmission efficiency between servers and storage devices.
Broadcast TV (CATV) system:
Used for distribution and reception of multi-wavelength signals to support HD video and broadband services.
Fibre to the Home (FTTH):
For distribution and aggregation of multi-user signals in fibre-optic access networks.
Industrial and Scientific Research Field:
For multi-wavelength optical experiment and test system.
In industrial automation, to support the transmission and monitoring of multi-channel optical signals.
Network monitoring and maintenance:
The ‘+1’ channel can be used to monitor network performance in real time and quickly locate points of failure.
