QSFP-40GE-LR4=

This Cisco QSFP-40GE-LR4= module provides a 40 Gigabit Ethernet connection over single-mode fiber, commonly used in data centers and enterprise networks. Built for long-distance communication, it supports transmission distances up to 10 kilometers using a 1310nm wavelength. Network engineers and IT professionals often find it suitable for backbone links or high-bandwidth uplinks between switches and routers.

Key Features

• Enables high-speed 40Gbps data transfer over single-mode fiber
• Operates effectively over distances reaching 10 kilometers
• Uses duplex LC connectors for secure and standardized fiber interfaces
• Compatible with Cisco QSFP+ ports and network equipment
• Supports 40GBase-LR4 Ethernet standard for consistent performance

This transceiver module is typically deployed in large-scale network environments where long-range, high-bandwidth links are necessary. Its ability to maintain stable connections over long distances helps keep critical infrastructure running smoothly without the need for signal repeaters or additional hardware.
