High Performance DWDM Multiplexers And OADM Module 2 Channels To 32 Channels

  GRACYFIBER's high-performance DWDM Mux/Demux and OADM series are passive expansion engines designed for high-speed, high-capacity optical communication networks. Perfectly suited to the stringent deployment requirements of metropolitan area networks, backbone networks, and 5G fronthaul/midhaul, this series strictly adheres to ITU-T C-band standards (C11–C64). From compact 2/4-channel OADM nodes to high-density 32-channel multiplexers, this solution enables telecom operators and cloud service providers to maximize the bandwidth potential of existing fiber optic cables without laying expensive physical fiber optic cabling, achieving smooth, exponential leaps in network capacity.

(Designed to overcome fiber optic resource bottlenecks and ensure high-speed signal integrity)

• Features: Full C-band ITU Grid (C11–C64) coverage and flexible channel spacing. Addresses pain points/value: Operating wavelengths cover 1525~1565 nm and support standard 100GHz and 200GHz channel spacing. This allows the module to seamlessly integrate into the vast majority of existing DWDM transmission architectures globally, helping network planners precisely allocate wavelength resources and achieve on-demand expansion of system capacity.
• Features: Ultra-low insertion loss and excellent channel isolation. Addresses pain points/value: Taking a 4-channel module as an example, its maximum insertion loss is only 1.8 dB; even for a high-density 32-channel module, the insertion loss is controlled within 4.8 dB. Combining the extremely high isolation of adjacent channels (≥ 30 dB) and non-adjacent channels (≥ 40 dB), it effectively guarantees the power budget for long-distance repeaterless transmission and completely eliminates crosstalk between dense wavelengths, providing a clean optical path environment for high-speed data streams.
• Features: Integrated 1310nm dedicated port and Monitor port address pain points/value: The ingenious port configuration, with a built-in independent 1310nm broadband port (1260~1360 nm), allows for seamless overlay and protection of existing 1310nm legacy services while expanding DWDM wavelength capacity. The dedicated Monitor port enables network operators to perform real-time, non-intrusive optical power fault diagnosis without interrupting backbone traffic.
• Features: Extremely low PDL ($≤ 0.5 dB) and excellent passband flatness (Ripple) address pain points/value: In 2/4/8-channel configurations, in-band flatness (Ripple) is as low as 0.3 dB, and polarization dependent loss (PDL) is ≤ 0.5 dB. This highly consistent optical characteristic is extremely friendly to cascaded EDFAs (Erbium-doped fiber amplifiers) in long-haul networks, preventing signal distortion and drastic degradation of the signal-to-noise ratio.
• Features: High optical power handling and industrial-grade stability address pain points/value: Withstands a maximum input optical power of 300 mW and operates stably in a temperature range of -5°C to 65°C, easily handling the thermal challenges and power surges posed by high-power laser arrays in data centers.
