Product information

Description

The StarTech.com J4858C 1000BASE-SX SFP Transceiver Module 10 Pack provides 1 Gbps fiber connectivity for 1000BASE-SX networks using multi-mode fiber with LC connectors. Each hot-swappable module supports a wavelength of 850 nm and a maximum optical reach of up to 550 m (1804 ft). Designed as a compatible replacement for HPE J4858C modules, this ten-pack is intended to simplify installation and maintenance in switches and routers that accept SFP modules.

Advantages

These SFP transceivers offer a compact SFP form factor with low power consumption (under 1.3 W), integrated Digital Diagnostics Monitoring (DDM), and an aluminum housing for durability. With a high MTBF of approximately 3,381,761 hours and hot-swappable operation, the modules minimize downtime during upgrades or replacements. The product is backed by StarTech.com’s lifetime warranty and lifetime multilingual technical support.

Suitable for

  • Upgrading or expanding 1 Gbps fiber ports on switches and routers
  • 1000BASE-SX multimode fiber network links up to 550 m
  • Data center access layer and campus backbone short-range fiber connections

Key specifications

  • Interface type: SFP (small form-factor pluggable)
  • Maximum data transfer rate: 1250 Mbit/s (1.25 Gbps)
  • Wavelength: 850 nm
  • Fiber type: Multi-mode fiber (MMF)
  • Connector: LC duplex
  • Maximum distance: 550 m (1804 ft)
  • Power consumption: < 1.3 W
  • DDM: Yes (Digital Diagnostics Monitoring)
  • MTBF: 3,381,761 hours
  • Pack quantity: 10 modules

How to use

Insert each SFP module into a compatible SFP port on an HPE-compatible switch or router while the device is powered on to take advantage of the hot-swappable feature. Connect LC-terminated multi-mode fiber cables to the module’s LC duplex connector, observing correct transmit/receive orientation. Verify link status and diagnostics through the network device management interface or use the module’s DDM readings for optical parameter monitoring.

Usage recommendations

Use OM3 or OM4 multimode fiber for optimal performance over longer reaches within the specified 550 m limit, keep fiber connectors clean to maintain signal quality, and ensure firmware and switch compatibility with HPE J4858C-compatible transceivers before deployment.
