Discover the benefits of 100G Bidirectional (BiDi) Optics for Data Centers
Demands for data and connectivity in data centers and enterprise networks are rising, network infrastructure is evolving to support higher bandwidth with minimal disruption. Traditional optical transceivers such as 1G SFP BiDi and 10G SFP+ BiDi help reduce fiber usage, but as network speeds increase, these legacy solutions no longer meet the performance and scalability of modern requirements.
To address this, 100G Bidirectional (BiDi) Optics have seen an increasing demand to provide higher-speed, with immediate cost-effective for upgrading the network capacity using existing fiber infrastructure.
What Are 100G Bidirectional (BiDi) QSFP28 Transceivers?
100G Bidirectional (BiDi) QSFP28 transceivers enable full-duplex transmission over a Single strand of singlemode fiber by using two optical wavelengths in opposite directions. This approach is based on Wavelength Division Multiplexing (WDM) technology, where a pair of transceivers simultaneously transmit and receive signals on two distinct wavelengths—typically 1271nm and 1331nm; 1291nm and 1331nm; 1304nm and 1309nm
Unlike traditional duplex optics, which require two fiber strands (one for transmit and one for receive), 100G BiDi transceivers reduce fiber usage by 50%, making them ideal for high-density environments and fiber-limited deployments.
Why Use 100G Bidirectional (BiDi) Optics?
The need for 100G connectivity is accelerating due to:
- Increasing east-west traffic between servers
- Greater virtual machine density
- Rapid adoption of cloud-native and AI workloads
For data centers already built with singlemode fiber, 100G Bidirectional (BiDi) optics offer several benefits:
- Maximize fiber utilization: Achieve 100Gbps using only one fiber strand.
- Reduce infrastructure cost: Avoid laying new fiber or re-cabling.
- Simplify cable management: Fewer fiber means less congestion in trays and ducts.
- Higher compatibility: Ideal for interconnects between switches, routers, and storage devices.
