Is the J4858C-AO compatible with HP equipment?

Yes, the J4858C-AO is 100% compatible with HP J4858C transceivers. It is factory-programmed with OEM-specific configuration data, uniquely serialized, and data-traffic tested to initialize and perform identically to HP equipment. It can be mixed and deployed with OEM or third-party transceivers for seamless network performance.

What is the maximum transmission distance?

The J4858C-AO supports up to 550 meters on 50/125µm multi-mode fiber and 500 meters on 62.5/125µm MMF. This reach is suitable for intra-building and campus network deployments. Distance varies based on fiber type and environmental conditions.

Does this transceiver support monitoring capabilities?

Yes, the J4858C-AO includes Digital Optical Monitoring (DOM) support, enabling real-time access to operating parameters such as optical power levels, temperature, and voltage. This allows proactive network management and rapid fault diagnosis without additional monitoring equipment.

What are the power consumption specifications?

The transceiver has low power dissipation below 800mW and operates on a single +3.3V power supply. This efficiency reduces heat generation and power budget requirements, making it suitable for high-density network deployments in data centers and enterprise environments.

What compliance certifications does this module hold?

The J4858C-AO is RoHS compliant (2002/95/EC 4.1&4.2, 2005/747/EC), TAA-compliant, and SFP MSA SFF-8074i compliant. These certifications ensure regulatory adherence for government and enterprise procurement and guarantee interoperability with standards-based network equipment.

Can the transceiver be installed without system downtime?

Yes, the J4858C-AO features a hot-pluggable SFP form factor, allowing field installation and removal without powering down the system. This capability minimizes operational disruption during maintenance, upgrades, or troubleshooting activities.

What operating temperature range is supported?

The transceiver operates reliably across 0–70°C environmental conditions, supporting both commercial and industrial deployment scenarios. This temperature range accommodates typical data center, enterprise network, and outdoor equipment enclosure environments.
