Fiber optic cold connectors can only connect to fiber optic cables
A fiber fast connector, also known as a mechanical splice or cold connector, is a field-installable connector that terminates fiber optic cables without requiring a fusion splicer. Active connection utilizes various fiber optic connectors (plugs and sockets) to connect site-to-site or site-to-cable. The typical attenuation is 1dB per connection. It allows connections. Fiber optic quick connector/cold connector The fiber optic quick connector/cold connector is a very innovative field-terminated connector, which contains factory-installed optical fiber, pre-polished ceramic ferrule and a mechanical splicing mechanism.

How many EPON ports can an OLT device connect to
One GPON port can connect to up to 128 GPON ONUs, and one EPON port can connect to up to 64 EPON ONUs. An 8-port OLT may suffice for a multi-dwelling unit (MDU) or small ISP, while a 16-port model supports larger residential communities or enterprise campuses. In fiber optic networks, especially in FTTx deployments, the number of Optical Network Units (ONUs) that a single PON port on an Optical Line Terminal (OLT) can support directly affects network planning, cost-efficiency, and service scalability. EPON is also the foundation for cable operators' business services as part of the DOCSIS Provisioning of EPON (DPoE) specifications. If a 1:64 fiber splitter is used, then one EPON port can connect to. The EPON OLT is the operator-side brain of a passive FTTH network: it manages up to 128 subscribers per PON port, in point-to-multipoint mode. ISPs must calculate the required number of PON ports according to subscriber growth plans.

100Mbps switch cannot connect to 1Gigabit switch
Make sure the computer you're connecting actually supports 1 Gbps Ethernet. Try to swap cables with another switch port. Understanding these is the first step toward resolving the issue: Gigabit Ethernet requires all 8 wires inside the cable to be intact and properly connected, whereas 100 Mbps only uses 4 wires. If the port is at fault, you'll get only 100 Mbps on it no matter what the cable length is and what's connected on the other end. The easiest way to do this in Windows is to right-click your network icon in your system tray and click either Network and Internet Settings, then click Network and Sharing Center, then click change adapter. Hey guys, I bought a Gigabit LS105G TP-Link switch for my home network, but after connecting my PC to it, my ISP Router says it's 100Mbit/s, even though the switch, and both cables used (ISP Router to Switch / Switch to PC) are 1000Mbit/s.

How far can a 100Mbps optical switch transmit data
Under 1550nm wavelength, 100Mbps and 1Gbps optical transceiver modules can transmit up to 160km, and 10Gbps optical transceiver modules can transmit up to 80km. )Due to the small core, only one optical mode is allowed to be transmitted. This characteristic enables single-mode fibers to transmit signals over long distances with low mode dispersion (mode dispersion is the time delay caused by the propagation of light signals along different paths). Compared with copper-based 100BASE-TX connections, it offers stronger EMI immunity, longer reach, and improved reliability in electrically noisy. Fiber optic cable transmission distance is determined by two primary physical factors that affect signal quality as light travels through the fiber medium. The greater the distance, the greater. Network cables transmit data via electrical signals (Ethernet, coaxial) or light pulses (fiber optic). In all cases, the medium (copper wires or glass fibers) introduces signal degradation over distance.
