Brief Introduction
The QSFP-40/100-SRBD is a dual-rate bidirectional optical transceiver supporting both 40G and 100G Ethernet over a single multimode fiber strand, enabling seamless network upgrades from 40G to 100G without replacing fiber infrastructure.
Detailed Description
This versatile QSFP28/QSFP+ compatible module uses bidirectional WDM technology to transmit 40Gbps (4x10G) or 100Gbps (4x25G) data streams over one MMF strand, reducing fiber costs by 50%. Compliant with IEEE 802.3bm and QSFP28 MSA standards, it achieves up to 100m on OM3 and 150m on OM4 fiber with ≤3.5W power consumption, ideal for high-density data centers and cloud networks.
Key Features
Dual-Rate Operation: Supports 40G-SR4 and 100G-SR4 standards
BiDi Technology: Single-fiber transmission via 850nm/900nm wavelengths
Hot-Swappable: Tool-free installation in switches/routers
Low Latency: <0.15ms for financial/HPC applications
Broad Compatibility: Works with Cisco Nexus 9000, Arista 7050X, Juniper QFX
Cost-Efficient: Eliminates fiber re-cabling for speed upgrades
