HPE X141 40G QSFP+ LC BiDi MMF XCVR

The HPE X141 40G QSFP+ LC BiDi MMF XCVR is a purpose-built optical transceiver designed to maximize bandwidth, reliability, and efficiency in modern data centers and enterprise networks. Built to meet the demanding needs of 40G uplinks, this transceiver leverages bidirectional (BiDi) technology to deliver high-density, scalable connectivity over multi-mode fiber. Ideal for rack-to-rack, spine-leaf, and top-of-rack deployments, the X141 is engineered to deliver consistent performance in spaces where fiber efficiency, low latency, and easy maintenance matter most. With its QSFP+ form factor and LC duplex connectors, it offers plug-and-play compatibility with a wide range of switches and routers while ensuring a smooth, hot-swappable installation that minimizes downtime. This transceiver is optimized for 150-meter MMF links, making it a strong choice for OM3/OM4 fiber infrastructure in data centers seeking to optimize cabling density without compromising link quality. If you’re looking for a reliable 40G solution that fits into existing MMF networks, the HPE X141 brings together robust build quality, proven bidirectional technology, and broad interoperability to help you scale your operations while reducing total cost of ownership.

• 40G BiDi performance on MMF: The HPE X141 delivers 40 Gbps of data throughput over multi-mode fiber using bidirectional wavelengths, enabling efficient uplinks and server-to-server connections without needing additional fiber strands. This BiDi approach reduces cable complexity and can lower cabling costs in dense data-center environments while maintaining high aggregate bandwidth for cloud, virtualization, and AI workloads.
• LC duplex QSFP+ transceiver: Designed for standard QSFP+ ports, the X141 uses a compact LC duplex connector configuration that is compatible with common switch and router interfaces. This design supports easy insertion, hot-swapping, and straightforward migration paths for networks upgrading from 10G or consolidating 40G deployments in a single chassis.
• 150-meter MMF reach: Optimized for OM3/OM4 multi-mode fiber, the X141 supports reliable 150-meter links in typical data-center topologies. This reach is ideal for mid-range distances between servers, top-of-rack switches, and aggregation layers, enabling flexible layouts without sacrificing signal integrity.
• Wide interoperability and ecosystem readiness: While built for HP networking products, the X141 adheres to standard QSFP+ BiDi specifications, enabling cross-vendor compatibility with many switches and storage networking devices that support 40G BiDi transceivers. This makes it a practical choice for hybrid environments or phased network refreshes where multiple vendors are present.
• Reliability, efficiency, and ease of deployment: The X141 is engineered for robust performance in data centers, with considerations for low power, thermal stability, and long-term reliability. Its hot-swappable design reduces maintenance windows, while its BiDi architecture helps minimize fiber management complexity and downgrade risks in dense rack configurations.

How to install HPE X141 40G QSFP+ LC BiDi MMF XCVR

Follow these steps to install the HPE X141 quickly and safely, ensuring optimal performance from day one:

• Power down or place the connected device into a safe maintenance state before handling the transceiver to protect both the port and the module.
• Inspect the QSFP+ slot for any debris and verify compatibility with your switch or router model. Confirm that the port is designed to accept QSFP+ modules and BiDi Bi-directional MMF operation.
• Align the X141 with the QSFP+ port, ensuring the orientation matches the slot keying. Gently insert the module until it seats securely with a positive click, indicating a proper connection.
• Connect the MMF fibers to the LC duplex connectors on the transceiver, ensuring clean, dust-free termini. Use proper fiber cleaning tools and technique to avoid insertion loss or back reflections.
• Power on the device, then verify link status indicators. Access the switch management interface to confirm the 40G interface is recognized and that it negotiates correctly with the connected device.
• Configure the interface for the desired 40G uplink settings (e.g., speed, flow control, and VLAN tagging) and run a basic connectivity test to validate throughput and stability over the expected 150-meter MMF link.

Frequently asked questions

• Q: What type of fiber does the HPE X141 use, and what is the recommended reach? A: It uses multi-mode fiber (MMF) and is designed for up to 150 meters on OM3/OM4 fiber, making it suitable for typical data-center uplinks and inter-rack connections.
• Q: What connector is on the transceiver? A: The module uses LC duplex connectors for MMF fiber, paired with a QSFP+ form factor for plug-and-play integration into compatible switches and routers.
• Q: Is this transceiver compatible with non-HPE switches? A: Yes, it is designed to be interoperable with standard QSFP+ BiDi 40G deployments; however, always verify firmware and vendor compatibility for non-HPE devices.
• Q: What is BiDi technology in this context? A: BiDi, or bidirectional transmission, uses two distinct wavelengths on a single MMF pair to send and receive data, enabling 40G throughput without requirements for extra fiber strands.
• Q: Do I need drivers or special software to use this transceiver? A: In most cases, no special drivers are required—the transceiver operates as a standard QSFP+ module and is auto-negotiated by the switch or router’s firmware. Ensure firmware compatibility and proper configuration for optimal results.
