AirLive 1000BASE-LX MiniGBIC Transceiver User Guide
Comprehensive guide for the AirLive SFP-LX-1.25G-20KM single-mode fiber transceiver, covering specifications, installation, and operational features.
Table of contents
Product Overview
The AirLive SFP-LX-1.25G-20KM is a high-performance, cost-effective single-mode SFP fiber transceiver designed for serial optical data communication. It supports data rates up to 1.25Gbps over distances of up to 20 kilometers. This module is engineered for single-mode dual-fiber applications and operates at a nominal wavelength of 1310nm. It is fully hot-pluggable, allowing for easy installation and replacement without powering down the host equipment.
Key Features and Applications
This transceiver is built for reliability and high-speed performance, incorporating advanced monitoring functions such as TX Disable control, TX-Fault, and RX_LOS (Loss of Signal) monitoring. It utilizes a duplex LC connector interface and is compliant with IEEE802.3z standards and Class I Laser safety requirements. The module is ideal for high-speed storage area networks, computer cluster cross-connects, and customized high-speed data pipes. It is suitable for various environments, including banks, airports, hotels, and industrial facilities.
Technical Specifications and Environment
The device operates within a temperature range of 0°C to +70°C and features excellent ESD protection and low electromagnetic interference (EMI). It requires a power supply voltage of 3.3V (typical) and has a maximum power consumption of 1.0W. The module supports Digital Diagnostic Monitoring (DDM), which provides real-time information about the fiber connection, making it significantly easier to identify faults or poor connections within the network infrastructure.
Installation and Maintenance
The SFP module is designed for seamless integration into compatible network switches and routers. Because it is hot-pluggable, it can be inserted into an SFP port while the device is running. Users should ensure that the fiber optic cables are clean and properly seated in the duplex LC connector to maintain signal integrity. The DDM functionality should be utilized via the host switch management interface to monitor optical power levels and ensure the link is operating within the specified parameters. If a link failure occurs, check the RX_LOS status and verify the fiber cable integrity.
