Frequently Asked Questions

What is the primary use case for the HPE X140 40G QSFP+ transceiver? +

The HPE X140 QSFP+ CSR4 transceiver is designed for high-density 40GbE connectivity within campus environments. It is ideal for bridging short-to-medium distance links between core switches and distribution layers, providing a reliable, high-bandwidth solution for data-intensive applications where standard multimode fiber runs are required.

What type of optical fiber and connector does the JH681A module utilize? +

This module utilizes MPO (Multi-fiber Push-On) connectors, which are standard for high-speed parallel optics. It is designed for use with multimode fiber (MMF) infrastructure. Ensure your existing cable plant is equipped with MPO/MTP interfaces and compatible multimode cabling to ensure a proper physical layer connection.

What is the maximum reach of the HPE X140 40G CSR4 transceiver? +

The JH681A transceiver supports a maximum reach of up to 300 meters over optimized multimode fiber. This distance makes it perfectly suited for inter-building links or large data room configurations where low latency and high throughput are required over moderate distances without needing expensive single-mode optics.

Does the JH681A transceiver require specific switch compatibility? +

This transceiver is specifically engineered for HPE networking hardware supporting the QSFP+ form factor. To ensure seamless operation and avoid link negotiation issues, it is recommended to verify that your specific HPE switch model is listed in the official compatibility matrix provided by the manufacturer.

What operating wavelength does the HPE X140 QSFP+ module use? +

The JH681A operates at an 850nm wavelength. This is the industry-standard wavelength for short-range multimode optical communications, allowing for efficient data transmission across the multiple strands of fiber bundled within the MPO interface required by the CSR4 standard.

How does the CSR4 standard improve link performance? +

The CSR4 (Client Short Reach 4) standard utilizes parallel optics technology to transmit data over multiple fiber lanes simultaneously. This approach allows the transceiver to achieve a consistent 40Gbps aggregate bandwidth while maintaining the thermal efficiency and low power consumption necessary for dense rack-mount environments.

Can I use this transceiver in a 10GbE network environment? +

While the X140 is a native 40GbE module, its ability to integrate into your network depends on the port capabilities of your specific HPE switch. Please check your hardware's documentation to see if it supports QSFP+ port breakout configurations, which might allow you to split the 40G port into four 10GbE lanes.

Is the HPE JH681A hot-swappable in HPE network equipment? +

Yes, the JH681A is designed for hot-swapping, allowing for seamless installation or replacement into active QSFP+ ports without powering down your switch. This feature is critical for maintaining high availability and minimizing network downtime during maintenance windows or hardware upgrades.

How can I obtain a bulk quote for multiple HPE X140 transceivers? +

For large-scale deployments requiring high quantities of the JH681A, please contact our dedicated sales team directly. We are experienced in handling bulk procurement requests and can provide competitive pricing structures tailored to your specific project needs. Reach out via our website to receive a formal quotation today.

Why should I purchase my HPE networking hardware from BuyRouterSwitch.com? +
