Ricetrasmettitore SFP compatibile hp J4860D 1G LC 70 km single-mode

SFP transceiver compatible with HPE Aruba, model J4860D, provides 1 Gbps data transmission over single-mode fiber with an LC connector and a reach of up to 70 km. The module is intended for insertion into standard SFP ports on switches, routers and media converters to establish long-distance Gigabit Ethernet links. It is designed to support point-to-point fiber connections in backbone, campus and carrier environments where single-mode fiber is used.

Advantages

This SFP module supports Gigabit Ethernet speeds over single-mode fiber and features an LC duplex interface for easy connection to standard fiber patch cables. Its 70 km optical reach enables long-distance links without intermediate regeneration, reducing the need for additional hardware. The transceiver is hot-pluggable, allowing installation or replacement without powering down network equipment, and is engineered to be compatible with HPE Aruba SFP ports to ensure predictable interoperability in mixed-vendor deployments.

Suitable for

• Long-distance backbone links between data centers or central offices
• Campus networks connecting buildings across extended sites
• Carrier and metropolitan area network (MAN) interconnects
• Edge-to-core fiber uplinks in enterprise and service provider networks

Key specifications

• Interface: SFP form factor with LC duplex connector
• Data rate: 1 Gbps (Gigabit Ethernet)
• Optical fiber type: single-mode (SMF)
• Maximum reach: up to 70 km over single-mode fiber
• Wavelength: typical single-mode optical wavelength suitable for long-reach links
• Hot-pluggable design for in-service replacement

How to use

Insert the SFP transceiver into an empty SFP port on a compatible switch or router until it latches securely. Connect LC single-mode patch cables to the transmit and receive ports, respecting the correct TX/RX orientation. Verify link status on the network device and configure the interface for 1 Gbps operation if required by the device software. Use appropriate optical attenuators or launch power settings if required to match fiber link loss and to ensure reliable signal levels over the 70 km span.

Recommendations

For stable long-distance performance, use single-mode fiber with appropriate connectors and maintain clean fiber end-faces. Verify compatibility with the network equipment vendor’s supported transceiver list and monitor link quality after installation. Keep spare modules and labeled patching to minimize downtime during replacements.
