The J4858B-C is a hot-pluggable SFP (Mini-GBIC) transceiver module that delivers 1 Gbps over multimode fiber using LC connectors, fully compatible with HP ProCurve switches.
Yes, the J4858B-C is engineered for seamless interoperability with HP ProCurve switch series that feature SFP slots, including 2510, 2520, 3400, 5400, and 8200 families.
The J4858B-C supports 50/125 µm and 62.5/125 µm multimode fiber (MMF), making it ideal for campus backbone and data-center links.
At 850 nm wavelength, the J4858B-C achieves reliable data transmission up to 550 meters over 50 µm MMF and up to 275 meters over 62.5 µm MMF.
The module operates at an 850 nm nominal wavelength, optimized for short-reach multimode fiber applications.
Simply align the LC connector latch, insert the module into the SFP slot until it clicks, and secure the fiber cable—no configuration changes are required.
Yes, the J4858B-C can be inserted or removed from an active switch without powering down, ensuring uninterrupted network uptime.
The transceiver supports a full-duplex data rate of 1.25 Gbps (1 Gbps Ethernet) for Fibre Channel and Ethernet applications.
It uses duplex LC connectors, providing a compact, reliable interface for multimode fiber links.
The module is rated for operation from 0 °C to 70 °C (32 °F to 158 °F), suitable for standard commercial environments.
The J4858B-C comes with a one-year limited warranty covering manufacturing defects and functional performance.
No, the J4858B-C is optimized for multimode fiber only; single-mode fiber requires an 1310 nm or 1550 nm SFP transceiver.
The transceiver draws a maximum of 0.8 W, minimizing thermal load in high-density switch configurations.
It features digital diagnostics monitoring (DDM) for real-time link parameters, enabling proactive maintenance and uptime assurance.
Yes, its small form-factor and low power profile make it ideal for high-density 1 Gbps port aggregation in data centers and wiring closets.
The J4858B-C matches HP’s performance and interoperability at a lower cost, offering the same specifications and compatibility with HP ProCurve switches.
