Know before you buy
Yes, the PSFP-11DT55K100 is designed to meet strict SFP specifications, ensuring broad compatibility with major networking equipment from vendors like Cisco, Brocade, and Juniper.
This transceiver is designed specifically for single-mode fiber applications. It utilizes an LC duplex connector, so you will need to ensure your cabling infrastructure supports LC-terminated single-mode fiber.
The enhanced digital diagnostics allow you to monitor real-time performance metrics such as optical output power, input power, temperature, and transceiver supply voltage. This helps in proactive troubleshooting and maintaining network stability.
No, this module is specifically engineered for 1G ZX Ethernet links with a maximum data transfer rate of 1000 Mbps. It is not compatible with 10G or higher speed network ports.
The combination of a Distributed Feedback (DFB) laser and an Avalanche Photodiode (APD) receiver provides the high signal integrity and sensitivity required to maintain a stable 1Gb connection over distances as long as 100 kilometers.
