Description

The QSFP-40G-LR4-S is a 40 Gigabit Small Form-F Factor Pluggable (QSFP+) transceiver designed for long-range data transmission over single-mode fiber (SMF). It supports 40 Gigabit Ethernet (40GbE) and is typically used in applications requiring long-distance connectivity in data centers, enterprise networks, and service provider networks.

Key Features:

• Data Rate: 40 Gbps (40 Gigabit Ethernet)

• Wavelength: 4 wavelengths at 1264.5 to 1337.5 nm (CWDM – Coarse Wavelength Division Multiplexing) for efficient transmission over long distances.

• Reach:

  • Up to 10 kilometers (10 km) over single-mode fiber (SMF).

• Connector Type: LC duplex connectors (used for single-mode fiber connections).

• Form Factor: QSFP+ (optimized for 40GbE applications).

• Power Consumption: Typically low, helping to maintain energy efficiency in long-distance network deployments.

Applications:

• Data Center Interconnects (DCI): Ideal for long-range interconnects between data centers located in different buildings or geographical locations, typically over single-mode fiber.

• Wide Area Network (WAN) Links: Used by service providers or large enterprises to establish long-distance 40GbE connections between remote locations.

• Metro Networks: Connecting devices across urban distances, where high-speed 40GbE links are required for efficient data transfer.

• Core Network Backbone: Connecting high-capacity core routers and switches within large-scale network infrastructures.

Benefits:

• Long-Range Connectivity: Supports a reach of up to 10 kilometers over single-mode fiber, enabling long-distance connections without the need for additional repeaters or amplifiers.

• High-Speed Performance: Delivers 40GbE connectivity, allowing for high-capacity data transmission and handling heavy bandwidth requirements.

• Cost-Effective for Long Distances: Single-mode fiber provides a more cost-effective solution for long-range 40G Ethernet connections compared to copper or multimode fiber-based solutions.

• Low Latency: Designed for high-performance applications that require low-latency communication, such as real-time data processing, cloud services, and data replication.

• Hot-Swappable: The QSFP+ transceiver can be easily inserted or removed without disrupting the system, making it easy to deploy or replace as needed.
