## Long description

The BlueOptics BO28C3443620DIN is a high-performance cSFP fiber optic transceiver module engineered for reliable 1.25 Gigabit Ethernet connectivity. This module is specifically designed to handle demanding data transmission tasks, offering a maximum data rate of 1250 Mbit/s over singlemode fiber. With its robust construction and support for extended temperature ranges, it ensures consistent network performance even in challenging industrial environments.
Advantages
This transceiver module provides the benefit of high-density connectivity through its cSFP form factor, allowing for efficient use of space in network hardware. The inclusion of Digital Diagnostics Monitoring (DDM) allows administrators to monitor real-time parameters such as optical power and temperature, facilitating proactive maintenance. Its ability to operate in extreme temperatures from -40°C to +85°C makes it a versatile solution for outdoor installations or industrial facilities where standard equipment might fail.
Suitable for
Industrial Ethernet networks
High-density fiber optic switching
Long-range data transmission up to 20 km
Demanding environments requiring temperature resilience
This module may not be suitable for applications requiring speeds higher than 1.25 Gigabit Ethernet or for use with multimode fiber cabling. It is specifically optimized for singlemode infrastructure and may not function correctly if integrated into hardware that does not support the cSFP standard.
Key specifications
Data transfer rate: 1250 Mbit/s
Interface: LC-Duplex
Transmission distance: Up to 20 km
Operating temperature: -40°C to +85°C
Fiber type: Singlemode
Form factor: cSFP
To use the BlueOptics BO28C3443620DIN, simply insert the module into a compatible cSFP port on your network switch or router. The device supports hot-swapping, meaning it can be installed or removed without powering down the host equipment. Once inserted, the link should be established automatically, provided the fiber optic cables are correctly connected to the LC-Duplex interface.
What to consider before purchase
Verify compatibility with your existing switch or router ports
Ensure your fiber infrastructure is singlemode
Confirm that the 20 km range meets your specific site requirements
Ensure that the fiber optic connectors are clean and free of dust before insertion to maintain optimal signal integrity and prevent damage to the transceiver optics.
