Keeplink Single-Mode Single-Fiber Transceiver

Page Content

The Keeplink Single-Mode Single-Fiber Transceiver is a gigabit optical module designed for long-distance, high-speed data transmission over single-mode fiber, typically supporting distances up to 20 km.

Overview

The Keeplink single-mode single-fiber transceiver is an SFP (Small Form-factor Pluggable) optical module that converts electrical signals into optical signals and vice versa, enabling network devices such as switches, routers, and media converters to communicate over fiber optic links . Unlike multimode transceivers, it uses a single-mode fiber core (approximately 9/125µm) and laser-based transmission to achieve long-distance communication with minimal signal loss .

Key Specifications

Data Rate: Gigabit Ethernet (1 Gbps)
Fiber Type: Single-mode fiber (SMF)
Transmission Distance: Typically up to 20 km, depending on optical power and network conditions
Wavelength: Commonly 1310 nm or 1550 nm for long-distance transmission
Connector Type: Usually LC or SC connectors, compatible with standard SFP slots
Hot-Swappable: Can be inserted or removed without powering down the network device

Applications

Keeplink single-mode single-fiber transceivers are ideal for:

Enterprise networks: Connecting buildings or campus networks over long distances
Telecommunications: Metro networks and backbone links
Data centers: Uplink connections between switches or routers
Fiber-to-the-Home (FTTH) deployments: Providing high-speed connectivity to residential or business subscribers

Advantages

Long-distance capability: Supports links up to 20 km, reducing the need for repeaters
Low attenuation: Laser-based transmission ensures minimal signal loss
Flexibility: Compatible with standard SFP ports, allowing easy upgrades or replacements
Compact design: Small form factor saves space in network racks or media converters

Considerations

Ensure the network device supports single-mode SFP modules
Verify the wavelength and distance requirements match your network design
Check for compatibility with existing fiber infrastructure, including connector type and fiber quality The Keeplink single-mode single-fiber transceiver provides a reliable, high-performance solution for long-distance optical networking, making it suitable for enterprise, telecom, and data center applications where stable gigabit connectivity over single-mode fiber is required .
