Fiber optic transceiver module BlueOptics SFP992-1ELH-BO 120000 m Aluminium

The BlueOptics SFP992-1ELH-BO is a single‑mode fiber optic SFP transceiver module designed for long‑range gigabit links up to 120000 m. The module uses an LC duplex interface and operates with 1550 nm wavelength for both transmitter and receiver, supporting 1000BASE‑ZX applications. Constructed with an aluminium housing and weighing approximately 20 g, it meets MSA SFP form‑factor specifications and is suitable for deployment in switches, routers, storage systems and other network platforms that accept standard SFP transceivers.

Advantages

The transceiver combines long‑reach capability with a compact SFP form factor and an aluminium body that contributes to mechanical robustness and thermal dissipation. It supports simultaneous transmit and receive over separate fibers via LC duplex connectors and is compatible with Ethernet and related high‑speed protocols at up to 1.25 Gbps. Production follows MSA standards and the module is engineered using quality optical and IC components to provide stable performance and an extended service life.

Suitable for

• Long‑distance single‑mode Ethernet links (1000BASE‑ZX)
• Interconnection between data center buildings and campus sites
• Upgrading or replacing SFP ports in switches, routers and storage systems
• Fiber backbone links requiring low EMI susceptibility and high availability

How to use

Insert the BlueOptics SFP992-1ELH-BO into an SFP port on compatible network equipment while the equipment is powered according to the manufacturer's guidance. Connect an LC duplex single‑mode patch cable, ensuring correct transmit/receive orientation. Verify link status and speed on the host device. If the host supports digital diagnostics (DDM/DOM), enable or read diagnostic parameters through the device management interface to monitor voltage, temperature, laser bias and optical power.

Recommendations

For optimal performance, use single‑mode LC duplex fiber and certified patch cords; avoid bending beyond the fiber's minimum radius and ensure connectors are clean before mating. Confirm that the target hardware supports 1000BASE‑ZX SFP modules and DDM/DOM if remote diagnostics are required. When replacing an existing module, match transmit/receive orientations and verify link integrity after installation.
