Disadvantages of Semi-Airtight Optical Modules
Higher Bit Error Rate (BER): Lower signal-to-noise ratio and timing jitter increase packet errors and retransmits. Lower optical output power / reduced receiver sensitivity: Link margin shrinks and previously stable links may drop.

What are the consequences of insufficient transmission distance of optical modules
This loss directly affects network performance by reducing data transmission efficiency, increasing error rates, and limiting the maximum transmission distance. When signal loss exceeds acceptable levels, it can cause slower speeds, data corruption, and even complete communication. In today's high-speed networking environments, SFP distance has become one of the most critical yet commonly misunderstood factors when designing fiber optic connections. Whether deploying enterprise switches, telecom backbones, or data center links, engineers often assume that speed (1G, 2. 5G, or. However, when long-distance optical modules are directly connected to short-distance optical fibers without attenuation, the optical components at the receiving end are easily damaged.
