User Manual
FAQ
What is the maximum distance supported by this SFP module?
The TN-GLC-LH-SM supports a maximum reach of 10 kilometers (6.21 miles) over single-mode fiber. This extended distance makes it suitable for connecting network equipment across campus environments, between buildings, or in metropolitan area networks without signal degradation.
Is this SFP module compatible with Cisco switches and routers?
Yes, this module is designed as a Cisco-compatible SFP transceiver. It interoperates with Cisco and other standards-based SFP ports, providing a reliable, hot-pluggable solution for Gigabit Ethernet uplinks and fiber connections without requiring vendor-specific licensing or configuration.
What type of fiber connector does this module use?
It uses an LC duplex connector, which is the industry standard for SFP optical modules. The LC connector offers a small form factor, secure locking mechanism, and low insertion loss, ensuring optimal optical performance and easy fiber management in high-density patch panels.
Does this SFP module support Digital Diagnostic Monitoring (DDM)?
Yes, the module includes DDM (also known as DOM) capabilities. This allows real-time monitoring of key parameters such as temperature, supply voltage, laser bias current, and transmitted/received optical power, enabling proactive network management and troubleshooting.
What is the data transfer rate of this SFP transceiver?
It operates at a full-duplex data rate of 1000 Mbps (1 Gigabit per second) using 1000Base-LX technology. This provides ten times the throughput of standard 100 Mbps Fast Ethernet, supporting high-bandwidth applications like video streaming, large file transfers, and VoIP traffic over fiber.
Is this module suitable for single-mode or multimode fiber?
This module is designed exclusively for single-mode fiber. Single-mode fiber uses a single wavelength of light to transmit data over long distances with minimal attenuation, making it ideal for the 10 km reach supported by this transceiver. It is not compatible with multimode fiber.
