Maximize Your Fiber Optic Network Efficiency

Unlock the full potential of your network with the Optical Fibre 1.25G Bi-Directional (BiDi) SFP Transceiver. This high-performance module is engineered to transmit and receive data over a single strand of single-mode fiber, effectively doubling your network's capacity without the need to install new cabling. By utilizing Wave Division Multiplexing (WDM) technology, this transceiver sends data on one wavelength (1310nm) and receives data on another (1550nm), making it a highly cost-effective solution for expanding your network reach up to 10 kilometers.

Real-Time Monitoring and Broad Compatibility

This hot-pluggable SFP module is equipped with Digital Diagnostics Monitoring (DDM) capabilities, providing real-time access to critical operating parameters such as optical power, temperature, and voltage. This feature allows for proactive network maintenance and troubleshooting, ensuring maximum uptime and reliability. Built to comply with Multi-Source Agreement (MSA) standards, this transceiver guarantees seamless compatibility with a wide range of networking equipment from various manufacturers.

Key Features:

  • 1.25Gbps Data Rate: Supports high-speed Gigabit Ethernet and other optical links.
  • Bi-Directional Technology: Transmits and receives data over a single fiber strand, saving on fiber costs.
  • 10km Transmission Distance: Reliably extends your network over long distances on single-mode fiber (SMF).
  • WDM Wavelengths: Features a Transmit (TX) wavelength of 1310nm and a Receive (RX) wavelength of 1550nm.
  • Single LC Connector: Simplifies connections and reduces cable clutter.
  • Digital Diagnostics (DDM): Enables real-time monitoring of module performance for enhanced network management.
  • Hot-Pluggable SFP Footprint: Allows for easy installation and replacement without shutting down your network.
  • MSA Compliant: Ensures broad compatibility with compliant switches, routers, and media converters.

Good quality
Size: Large, Color: (035) Steel / White / Black
These are a bit thicker then a compression sock and they come up higher on the ankle than a no-show sock normally does. They are very comfortable and soft.

I stay on your foot they don’t slip in your shoe
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
This is the only socks I wear Under Armour because they stay in place I wear a size 8, but they’re more comfortable with a large instead of a medium, but I wear both because I have them already and you can pull them to stretch them out a little bit
