Product information

Description

The BlueOptics 551121-BO is a high-performance SFP fiber optic transceiver module engineered for reliable data transmission in Fast Ethernet, Fibre Channel, and SONET/SDH environments. This module facilitates stable network connectivity with a maximum data transfer rate of 155 Mbit/s and is capable of reaching distances of up to 80 kilometers over single-mode fiber. Designed for seamless integration, it features a standard LC connector and a durable silver housing, ensuring long-term operational stability in professional networking hardware.

Advantages

This transceiver module offers exceptional reliability with a high mean time between failures of one million hours, making it an ideal choice for critical network infrastructure. Its hot-swap and hot-plug capabilities allow for easy installation and maintenance without the need to power down network equipment. The module is fully compliant with international standards, ensuring broad compatibility with various switches, routers, and storage systems while maintaining consistent signal integrity over long distances.

Suitable for

  • Fast Ethernet network connections
  • Fibre Channel storage area networks
  • SONET/SDH telecommunications infrastructure
  • Long-range fiber optic data transmission

This module may not be suitable for high-speed networks requiring data rates exceeding 155 Mbit/s, such as Gigabit Ethernet or 10G connections. Additionally, it is specifically designed for single-mode fiber applications and will not function correctly if used with multi-mode fiber cabling.

Key specifications

  • Data transfer rate: 155 Mbit/s
  • Maximum transmission distance: 80 km
  • Connector type: LC
  • Interface: SFP
  • Weight: 20 g
  • Color: Silver

To use the BlueOptics 551121-BO, simply insert the module into an available SFP port on your compatible network device. Ensure that the fiber optic cable is clean and properly terminated with an LC connector before plugging it into the transceiver. The device supports hot-swapping, meaning it can be inserted or removed while the equipment is powered on, though it is recommended to verify your specific hardware documentation for any port configuration requirements.

What to consider before purchase

  • Verify that your network hardware supports SFP modules with 155 Mbit/s speeds.
  • Ensure your fiber optic cabling infrastructure is single-mode to match the transceiver specifications.
  • Check the port availability on your switch or router.
Usage recommendations: Always handle the fiber optic connector with care and keep the dust cap on when the module is not in use to prevent contamination of the optical interface.
