Optický transceiver modul HPE X142 40G QSFP+ MPO SR4

The HPE X142 40G QSFP+ MPO SR4 fiber optic transceiver module delivers 40 Gbit/s connectivity over multimode fiber at 850 nm. Designed for data center environments, this HPE (HP Enterprise) transceiver (MPN JH231A, EAN 0889296046301) is MSA-certified and compatible with HP 5400R zl2 switches, providing reliable high-bandwidth links for aggregation and server-to-switch connections.

Advantages

This QSFP+ MPO SR4 module supports a maximum data transfer rate of 40000 Mbit/s and uses a standard QSFP+ interface for straightforward installation and interoperability. MSA certification ensures compatibility with a range of switch platforms, while the MPO connector and SR4 optics enable short-range, high-density fiber connections suitable for modern data center topologies.

Suitable for (tasks / use cases)

• Data center high-speed uplinks and aggregation
• Server-to-switch connectivity in short-reach multimode fiber environments
• Top-of-rack (ToR) and leaf-spine architectures requiring 40G links
