HPE JC859A 10-G SFP+ SR Transceiver Module

HPE JC859A 10-G SFP+ SR Transceiver Module

Overview

The HPE JC859A is a hot-swappable 10-Gigabit SFP+ optical transceiver made for short-range multimode fibre (MMF) applications in data-centres, such as switch-to-switch or server-to-top-of-rack links. It supports the IEEE 802.3ae 10GBASE-SR specification at an 850 nm wavelength and enables link distances up to approximately 300 metres over OM3 multimode fibre. The module fits into standard SFP+ ports on HPE switches and compatible hardware, offering duplex LC connectivity and supporting digital diagnostics monitoring (DDM/DOM) for real-time optical parameter feedback. Use it in high-density rack environments where fibre trunks connect aggregation switches or where short multimode runs are in place, rather than long single-mode links.

Key Features

• 10 Gbps data rate over multimode fibre for demanding rack-to-rack or switch-to-switch connectivity.

• Up to ~300 m reach on OM3 multimode fibre using 850 nm laser—suitable for intra-data-centre short-haul links.

• Duplex LC connector ensures standard multimode patch-cord compatibility in most racks.

• Supports Digital Diagnostics Monitoring (DDM) allowing real-time monitoring of optical parameters (e.g., TX/RX power, temperature).

• Hot-pluggable SFP+ form-factor lets you swap modules without powering down the switch, ideal for live upgrade environments.
