Product information

Description

The SFP Transceiver Module StarTech.com J4859C is a compatible replacement for HPE J4859C modules, providing 1 GbE connectivity over single-mode and multi-mode fiber for 1000BASE-LX networks. Operating at a wavelength of 1310 nm with a maximum nominal data rate of 1.25 Gbps (1 Gbps working throughput), the module supports distances up to 10 km on single-mode fiber and up to 1 km on multi-mode fiber. It uses an LC connector, consumes less than 1 W, includes Digital Diagnostics Monitoring (DDM) and is hot-swappable for easy field upgrades.

Advantages

This StarTech.com SFP module offers compatibility with HPE devices while providing DDM support for real-time monitoring, low power consumption, and hot-swappable installation to minimize network downtime. The module is compact and FCC/UL/CE certified, and StarTech.com provides a lifetime warranty and multilingual technical support.

Suitable for

1 GbE fiber uplinks between switches and routers
Campus and enterprise backbone links up to 10 km on single-mode fiber
Short-distance fiber connections within wiring closets or data centers using multi-mode fiber (up to 1 km)
Replacement or spare inventory for HPE J4859C-compatible equipment

Key specifications

Interface type: SFP (LC)
Wavelength: 1310 nm
Maximum data transfer rate: 1.25 Gbps (supports 1 Gbps operation)
Maximum distance: 10 km (single-mode), 1 km (multi-mode)
Power consumption: <1 W
MTBF: 3,092,408 hours
Digital Diagnostics Monitoring (DDM): Yes
Dimensions: 14 × 57 × 13 mm
Weight: 0.016 kg

How to use

Ensure the transceiver is compatible with your HPE switch or router and that the device is powered on. Insert the SFP module into an available SFP port until it clicks into place. Attach the appropriate LC-terminated single-mode or multi-mode fiber cable, taking care to observe correct transmit/receive orientation. The module is hot-swappable, so it can be installed or removed without powering down the host equipment; allow the device to negotiate link parameters and verify link status on the host interface.

Usage recommendations

For reliable performance, use quality LC fiber cables matched to the selected fiber type (single-mode or multi-mode), keep fiber connectors clean, and verify supported transceiver firmware/compatibility on HPE devices. Observe standard ESD precautions when handling the module.
