V over IP networks are designed to transport large volumes of audiovisual data with minimal latency and maximum reliability. However, these networks also impose unique demands on the hardware—especially on the fiber-optic modules that form the backbone of this infrastructure. In this blog, I discuss the specific risks AV over IP poses for the lifespan of SFP, SFP+, SFP28, and QSFP modules.

In AV over IP networks, transceivers often run continuously at 90–100% of their capacity. Think of 24/7 video streams, live camera feeds, or multichannel audio. This constant load results in:
A rule of thumb in electronics: every 10°C temperature increase halves the lifespan of components. At 85°C, the failure rate is up to five times higher than at 40°C [1].
In AV environments, downtime is rare. While an IT network might be idle at night, an AV backbone in a hospital or theater runs day and night. This means:
Modules operating under full load wear out faster than identical modules in less demanding environments.
AV over IP networks often push modules to their maximum capacity. For example:
In such scenarios, the link budget is tight. Even slight degradation in laser power can immediately lead to:
At higher speeds, tolerances are smaller—what works at 1 Gbps can be catastrophic at 25 or 100 Gbps.
AV installations are often located in challenging environments:
Unlike data centers with air conditioning and dust filters, AV locations are often thermally and physically harsher for modules. This increases the risk of:
In such situations, industrial-grade modules with higher temperature tolerance are recommended.
AV over IP networks present unique challenges for fiber-optic modules. The combination of high load, continuous operation, maximum data rates, and less-than-ideal environments increases the risk of accelerated wear. This doesn’t mean modules are unsuitable—but they do require more attention and monitoring.
In the next blog, we’ll explore how maintenance and monitoring can extend the lifespan of your modules and prevent failures.
