Fiber optic SFP transceiver module BlueOptics J9143-61101-BO 20000 m

The BlueOptics J9143-61101-BO is a single‑mode fiber SFP transceiver module designed for reliable optical data transmission over distances up to 20,000 m. Housed in an aluminum enclosure and weighing approximately 20 g, this SFP conforms to MSA form factor standards and provides a compact solution for 1000BASE‑BX‑U applications with an LC simplex connector. The module implements separate transmit and receive wavelengths for unidirectional operation over a single fiber and supports line rates up to 1.25 Gbit/s, making it suitable for Ethernet and Fibre Channel over Ethernet links in compatible network hardware.

Advantages

The transceiver combines a lightweight, corrosion‑resistant aluminum body with industry‑standard optics and electrical interfaces to deliver long reach and stable performance. It is manufactured to MSA specifications and is compatible with major HPE/H3C platforms that accept the equivalent 1000BASE‑BX‑U SFP, enabling interoperable replacements without requiring hardware modification. Built‑in digital diagnostics (DDM/DOM) allow remote monitoring of supply voltage, laser bias current, transmit power, receive power and temperature for simplified maintenance and troubleshooting.

Suitable for

• Long‑reach single‑mode fiber links up to 20 km
• Ethernet and Fibre Channel over Ethernet connections at 1.25 Gbit/s
• Switches, routers, storage systems and other network devices that support 1000BASE‑BX‑U SFP modules
• Environments where electromagnetic immunity and low latency are required

Key specifications

• Form factor: SFP (MSA compliant)
• Maximum link distance: 20,000 m (single‑mode fiber)
• Data rate: up to 1.25 Gbit/s
• Connector: LC simplex
• Transmit wavelength: 1490 nm (typical for BX‑U transmit)
• Receive wavelength: 1310 nm (typical for BX‑U receive)

• Weight: approx. 0.02 kg
• Digital diagnostics: DDM/DOM (SFF‑8472 compliant)

How to use

Insert the SFP module into a compatible SFP port on the target device until it locks into place, then connect an LC simplex single‑mode fiber patch cord with correct polarity. Ensure that the host device supports 1000BASE‑BX‑U optics and, if required, enable or verify DDM/DOM monitoring in the device management interface to read real‑time diagnostic parameters. For a bidirectional link, use a corresponding BX‑U transceiver at the remote end with matching wavelength orientation. Follow standard ESD precautions and avoid contamination of optical endfaces; inspect and, if necessary, clean connectors before mating.

Usage recommendations

To achieve optimal performance and longevity, pair the module with single‑mode fiber cabling and high‑quality LC connectors, verify compatibility with the host device firmware, and use the DDM/DOM function for ongoing link monitoring. Store unused modules in protective caps and in a dry, static‑free environment.
