Módulo transceptor SFP BlueOptics 943 042-001-BO 1550 nm 70000 m

The BlueOptics 943 042-001-BO SFP transceiver module is a single‑mode optical transceiver designed for long‑distance 1000BASE‑ZX Ethernet links. Operating at a 1550 nm wavelength and supporting up to 70,000 m (70 km) reach, this compact module uses an LC duplex connector and conforms to MSA SFP mechanical and electrical specifications. The module weighs approximately 20 g and is intended for use in compatible switches, routers and storage systems that accept standard SFP pluggable optics.

Advantages

The module delivers long‑reach single‑mode transmission at 1550 nm with a small form factor, enabling straightforward installation in SFP ports. It supports digital diagnostics (DDM/DOM) when the host hardware exposes the interface, allowing monitoring of parameters such as temperature, supply voltage, laser bias current and optical power. Built to MSA standards, the transceiver is interoperable with equipment from multiple vendors and is suitable for network designs requiring low electromagnetic interference and extended fiber runs.

Suitable for

• Long‑distance 1 Gbps Ethernet links over single‑mode fiber
• Interconnection between switches, routers and storage systems across campus or metropolitan networks
• Fiber backbone segments and point‑to‑point optical links up to 70 km

How to use

Install the BlueOptics SFP transceiver into a compatible SFP slot on your network device while following the device manufacturer’s hot‑plug and handling guidelines to avoid static discharge. Connect a single‑mode LC duplex patch cord to the module and its remote counterpart, ensuring correct transmit/receive alignment. Configure the host interface as required by your network equipment; many platforms will detect SFP modules automatically. If available, enable and read DDM/DOM parameters via your management interface or CLI to monitor link health and optical performance.

Recommendations

Use quality single‑mode fiber and LC duplex patch cords rated for long‑reach applications, keep connectors clean to preserve optical performance, and verify that the host device firmware supports 1000BASE‑ZX and DDM/DOM for full functionality. For critical links, perform end‑to‑end power budget calculations and test the link at deployment to confirm margin and stability.
