Optical Transceiver HP Enterprise X140 40G QSFP LC LR4 SM

HP Enterprise X140 40G QSFP LC LR4 SM optical transceiver (MPN JG661A-RFB) provides 40 Gbps aggregated bandwidth in a QSFP form factor for single‑mode fiber links. The module uses LC connectors and LR4 wavelength division multiplexing to support long‑reach fiber connections. Designed for compatibility with HPE equipment, it is intended for data center uplinks, campus backbone links and other network segments requiring high‑speed, long‑reach single‑mode fiber connectivity.

Advantages

The HP Enterprise X140 40G QSFP LC LR4 SM transceiver delivers high aggregated throughput in a compact QSFP package while using standard LC duplex interfaces. Its LR4 multiplexing enables transmission over single‑mode fiber at extended distances with a single module, reducing the need for multiple parallel fibers. The transceiver is engineered for interoperability with compatible HPE devices and supports standard 40G Ethernet links, simplifying deployment in existing HPE network environments.

Suitable for

• Data center uplinks and spine connections requiring 40 Gbps capacity
• Campus backbone links over single‑mode fiber
• Long‑reach inter‑site fiber connections where LR4 wavelength multiplexing is required
• Replacement or expansion modules in HPE-compatible network switches and routers

How to use

Install the HP Enterprise X140 40G QSFP LC LR4 SM transceiver into a compatible QSFP port on an HPE or supported network device following the device manufacturer’s hot‑swap and handling procedures. Ensure that the target switch or router firmware and compatibility lists include the MPN JG661A-RFB. Connect single‑mode LC fiber cables to the transceiver’s LC interfaces and verify link status, speed negotiation and optical parameters through the host device management interface. Observe electrostatic discharge (ESD) precautions and keep protective dust caps on fiber connectors when not in use.
