Product Overview
The GQ5000‑G42SC series fiber optic transceivers (also known as fiber optic switches) convert between Ethernet electrical and optical interfaces. This transceiver can be configured with two Gigabit Ethernet electrical ports and four Gigabit optical ports; the four optical ports can connect to four remote fiber optic transceivers, enabling point‑to‑multipoint networking. It extends Ethernet transmission distances from 100 meters over copper cabling to 550 meters (multimode fiber) or 80 kilometers (single‑mode fiber). It easily interconnects multiple host servers, repeaters, hubs, and terminals with numerous end devices. Featuring a mature switching core, a variety of fiber optic interfaces, and support for hot swapping, it offers flexibility, efficiency, and reliability. It is ideally suited for high‑performance, high‑reliability network environments such as telecommunications, broadcasting, broadband networks, and high‑definition video surveillance systems.
Product Features
◆ Supports two 10/100/1000M adaptive electrical ports and four Gigabit optical ports (single-fiber/dual-fiber optional)
◆ Supports full-duplex IEEE 802.3x flow control and half-duplex backpressure flow control, with auto-negotiation for either half- or full-duplex operation.
◆ Multimode transmission distance can reach up to 550 meters, while single-mode transmission distance can extend as far as 80 kilometers.
◆ Features include broadcast storm protection, traffic balancing, collision isolation, and error detection.
◆ Employs high-performance switching chips and large-capacity buffers.
◆ High-quality laser components exhibit excellent optical performance, electrical characteristics, and thermal stability.
◆ The circuit layout is scientifically designed, with strong anti-interference capabilities, effectively protecting against lightning strikes.
◆ Comprehensive status indicator lights ensure that the operating status is immediately clear at a glance.
◆ External professional switching power supply, ensuring safety and stability; overall power consumption is less than 5 W.
◆ Built-in lightning protection circuitry, which can significantly reduce damage caused by lightning-induced surges.
