As bandwidth demands explode, 100G QSFP28 modules have become the backbone of modern data centers and 5G networks. But traditional dual-fiber solutions require twice the fiber cabling, escalating costs and complexity. Enter single fiber QSFP28 modules—a game-changer using BiDi (Bidirectional) technology to transmit 100G data over one fiber strand. By leveraging different wavelengths (e.g., 1271nm/1331nm) for upstream/downstream traffic, these modules cut fiber infrastructure costs by 50% while maintaining full 100G performance.
➤ How Does 100G Single Fiber Transceiver Work? (The BiDi Principle)
Unlike standard duplex transceivers requiring two fibers (one Tx, one Rx), single fiber modules use Wavelength Division Multiplexing (WDM). They employ two different wavelengths (colors) of light:
Transmit (Tx): Sends data using one specific wavelength (e.g., 1271nm).
Receive (Rx): Listens for incoming data on a different wavelength (e.g., 1331nm).
A special filter (WDM coupler) inside the module combines and separates these signals onto the single fiber strand. This Bi-Directional (BiDi) communication is the core innovation.
➤ Why Choose 100G Single Fiber Modules? Key Advantages:
Double Your Fiber Capacity: Maximize ROI on existing single mode fiber plant. Avoid costly new fiber runs.
Significant Space Savings: Reduce fiber cabling density in racks and conduits. Crucial for high-density data centers and space-constrained deployments.
Cost Reduction: Lower costs associated with fiber purchase, installation, and management.
Simplified Network Design & Management: Easier cable management and reduced points of failure.
Future-Proofing: Efficiently scale bandwidth without constant physical infrastructure upgrades. Ideal for enterprise networks, 5G fronthaul, and FTTx applications.
