Brief Introduction
The QSFP-40G-SR-BD is a bidirectional 40G QSFP+ optical transceiver designed for high-density data center connectivity, enabling 40Gbps transmission over a single multimode fiber strand for cost-effective network upgrades.
Detailed Description
This hot-swappable transceiver uses wavelength division multiplexing (WDM) technology to transmit 40G Ethernet data through one MMF strand, reducing fiber infrastructure costs. Compliant with IEEE 802.3ba and QSFP+ MSA standards, it supports link distances up to 150m (OM4) and 100m (OM3) with low power consumption (≤1.5W), ideal for switch-to-switch connections in cloud computing and enterprise networks.
Key Features
Bidirectional Technology: Dual wavelengths (850nm/900nm) on single fiber strand
High Compatibility: Works with Cisco, Juniper, Arista, and Brocade switches
Low Latency: <0.1ms for high-frequency trading and real-time applications
Energy Efficient: 1.5W max power consumption
Duplex LC Connector: Simplified cable management
Extended Reach: 100m (OM3) / 150m (OM4) multimode fiber support
