Bidirectional SFP limitation-Why isn't more fiber ...
Bidirectional (BiDi) SFP transceivers utilize Wavelength Division Multiplexing (WDM) to transmit and receive data simultaneously over a single strand of fiber optic cable, doubling fiber capacity and reducing cabling costs by 50%. They operate using paired wavelengths (e.g., 1310nm/1490nm or 1310nm/1550nm) to manage upstream and downstream traffic, typically supporting distances up to 120 km. 
Key Features and Benefits 
  • Single Fiber Usage: Unlike traditional dual-fiber SFPs, BiDi modules use one simplex LC connector for both TX (transmit) and RX (receive).
  • WDM Technology:
