SFP transceiver module BlueOptics SFP992-1LH+-BO 1250 Mbit/s 1550 nm

The BlueOptics SFP992-1LH+-BO is an SFP fiber optic transceiver module designed for single-mode links at a wavelength of 1550 nm with a maximum data rate of 1250 Mbit/s. Housed in a compact metal casing and operating from a 3.3 V supply, the module provides a lightweight (2 g) solution for long-reach Ethernet and compatible optical applications. The transceiver is built to MSA form-factor standards, supports LC duplex connections, and implements 1000BASE-ZX optical transport characteristics for distances up to tens of kilometers depending on link design and fiber type.

Advantages

The module offers compatibility with common 1000BASE-ZX platforms and follows MSA specifications for hot-pluggable SFP use, enabling straightforward integration into switches, routers and other networking equipment. Its metal housing enhances thermal performance and mechanical stability, while a low weight and standard electrical interface simplify installation. Built with high-quality optical and electronic components, the transceiver is intended for reliable operation and extended service life in production networks.

Suitable for

• Long-distance single-mode Ethernet links (1000BASE-ZX)
• Interconnection of switches, routers and storage systems
• Telecommunications and carrier-class point-to-point links
• Network upgrades or replacements where Siemens SFP992-1LH+ compatibility is required

Key specifications

• Interface type: SFP (pluggable transceiver)

• Maximum data transfer rate: 1250 Mbit/s (1.25 Gbit/s)
• Connector: LC duplex
• Power supply: 3.3 V input
• Housing: metal
• Weight: approx. 2 g
• Supported protocols: Ethernet / Fibre Channel over Ethernet / SDH/SONET up to 1.25 Gbit/s
• Operating distance: suitable for long-reach single-mode links (see system link budget for exact range)
• Digital diagnostics: DDM/DOM per MSA SFF-8472 (if supported by host hardware)

How to use

Ensure the host device supports MSA SFP modules and the desired protocol (e.g., 1000BASE-ZX). With the host powered according to vendor guidelines, insert the BlueOptics SFP992-1LH+-BO into a compatible SFP slot until it latches. Connect LC duplex single-mode fiber patch cords observing correct transmit/receive orientation. Verify link status through the host device and, if required, enable or read DDM/DOM parameters from the management interface. Follow the equipment manufacturer's instructions for hot-plugging and electrostatic discharge precautions.

Usage recommendations

Use high-quality single-mode fiber and LC duplex patch cords, confirm host compatibility for Siemens SFP992-1LH+ equivalents, and validate the optical link budget for your required distance. If remote diagnostics are needed, ensure the host supports DDM/DOM per SFF-8472 to monitor voltage, temperature, transmit/receive power and laser bias current.
