4CH O-Band CWDM Multiplexer Module (1271~1331nm)

4CH O-Band CWDM Multiplexer Module (1271~1331nm)

1. Features

• Ultra-wide operating temperature range from -55°C to 85°C for deployment in extreme environments.

  
  

• Delivers low insertion loss (≤1.5 dB) and low polarization dependent loss (≤0.3 dB) for consistent signal integrity.

  
  

• Engineered for high channel isolation, achieving ≥30 dB for adjacent channels and ≥40 dB for non-adjacent channels.

  
  

• Features ruggedized 2.0mm armored fiber tubing to provide maximum mechanical protection.

  
  

• Highly compact module footprint measuring just 37.5 × 12.8 × 6.5 mm.

  
  

2. Applications

• Coarse Wavelength Division Multiplexing (CWDM) network architectures.

• Industrial and harsh environment optical communication systems.

• Specialized multi-signal routing, including visible (1271nm), infrared (1291nm), and imaging (1311nm) transmission applications.
