Kuitu-SFP-lähetin-vastaanotin BlueOptics J4860-69201-BO 80 000 m

The BlueOptics J4860-69201-BO is a single‑mode fiber optic SFP transceiver designed for long‑distance 1.25 Gbit/s optical links up to 80,000 meters. Housed in aluminium and weighing approximately 20 grams, this compact SFP module uses LC duplex connectivity and is intended for integration into SFP‑compatible network equipment that supports 1000BASE‑ZX protocol. The module supports optical transmit and receive at 1550 nm and includes Digital Diagnostic Monitoring (DDM/DOM) support when the host hardware enables this feature.

Advantages

This SFP transceiver follows MSA standards and is compatible with systems that accept the referenced module, providing predictable electrical and optical interfaces. The aluminium housing offers mechanical protection and heat dissipation in a lightweight form factor. Components are selected for stable optical performance over long distances, and the module is suitable for continuous operation in network environments where long‑reach single‑mode fiber links are required.

Suitable for

• Long‑distance uplinks between switches and routers over single‑mode fiber
• Inter‑site connectivity across campus or metropolitan links
• Storage and server interconnects where 1.25 Gbit/s optical links are needed
• Replacement or expansion of SFP ports in compatible network hardware

Key specifications

• Form factor: SFP (Small Form‑Factor Pluggable)
• Protocol: 1000BASE‑ZX, up to 1.25 Gbit/s
• Maximum reach: up to 80,000 m over single‑mode fiber
• Wavelength: 1550 nm (transmit and receive)
• Connector type: LC duplex
• Housing material: aluminium
• Weight: approximately 0.02 kg
• Digital Diagnostic Monitoring (DDM/DOM): supported when enabled by host hardware

How to use

Install the transceiver into an empty SFP port of compatible networking equipment until it clicks into place, taking care to follow the device manufacturer’s hot‑swap and electrostatic discharge guidelines. Use single‑mode LC duplex patch cords to connect the module to the far‑end transceiver, ensuring correct Tx/Rx orientation. If monitoring is required, enable and query the DDM/DOM functions via the host device management interface when the platform supports it. Verify link status and optical power levels after installation.

Recommendations

For optimal long‑reach performance, use quality single‑mode fiber and LC duplex patch cords, keep connectors clean, and verify that the host device officially supports 1000BASE‑ZX SFP modules and DDM/DOM features. Observe manufacturer temperature and handling limits and perform optical power checks during installation and maintenance.
