Packet loss occurs when the device is connected to the switch
Packet loss can occur if any link in the chain has issues: Local Devices (e., PC, network card): Driver anomalies, aging network cards, or resource exhaustion. Access Layer (switches): Port congestion, broadcast storms, or loops. The first thing to do when troubleshooting it is to isolate where the loss is occurring. On a PC: To confirm if packet loss is occurring: This will ping the address. If you are experiencing packet loss or slow network performance on your local area network (LAN), you may need to troubleshoot your LAN switch. A LAN switch is a device that connects multiple devices on a network and forwards data packets based on their destination addresses. Imagine ordering a desk that ships in five boxes. Boxes 1, 2, 4, and 5 arrive undamaged, but box 3—containing every last screw, bolt, and connector, of course—has gone missing in logistics-land. But I have 2 hypotheses: The CAT5e cable between switch and modem cannot handle the traffic of 6 routers/apartments. This can result in various issues, including reduced network efficiency, application failures, and degraded quality of service for real-time applications such as VoIP and video.

64 Splitter Loss
Theoretical Loss = 10 * log10 (64) ≈ 10 * 1. 06 dB This calculation gives you the absolute minimum possible loss you would experience on each output port if the splitter were perfectly efficient and distributed the power flawlessly. These are known as passive optical splitters, and they perform the function. Optical splitters play a crucial role in Fiber to the Home (FTTH) Passive Optical Network (PON) systems, efficiently distributing a single optical signal to multiple destinations. The split ratio and insertion loss are two key parameters defining their performance. The choice of split ratio—1×2, 1×4, 1×8, 1×16, 1×32, or 1×64—directly impacts optical power budget, network reach, subscriber density, and long-term expansion capability.

Reasons for the low return loss of optical splitters
See below for how OTDRs measure reflectance and return loss. Mechanical splices have index matching gel to prevent reflections. In fiber optic networks, particularly in FTTx (Fiber to the x) and PON (Passive Optical Networks) deployments, splitters play a central role in distributing the optical signal from a single source to multiple destinations. When high-speed signals enter or exit a part of an optical fiber, such as an optical fiber connector, discontinuity and impedance mismatch may cause reflection, which is the return loss of an optical fiber.
