Cisco QSFP-40G-ER4 Optical Transceiver Module (SMF, 1310nm, 40km, LC, DOM)

The Cisco QSFP-40G-ER4 Optical Transceiver Module is typically deployed in large-scale networking environments requiring long-distance, high-bandwidth connectivity. Networking teams in data centers and enterprise IT infrastructure will find this module effective for extending connections across campus or between facilities using single-mode fiber.

How It's Used:

• Facilitates 40Gbps uplinks between data center aggregation switches and core routers in multi-rack deployments.
• Supports high-throughput storage area network (SAN) connections over extended distances in enterprise data centers.
• Enables inter-building network links within geographically dispersed campus environments for enterprise IT.
• Integrates with virtualization environments requiring low-latency, high-speed fiber connectivity for server clusters.
• Provides backbone connectivity for service provider networks needing reliable, long-reach fiber transmission.

This transceiver module enhances network scalability and operational efficiency by delivering consistent high-speed links over distances up to 40 kilometers. Its compatibility with digital optical monitoring allows IT teams to maintain optimal network performance and quickly identify issues within complex fiber infrastructures.
