Huawei Gigabit Optical-to-Electronic Port Module Self-operated

Huawei Gigabit O/E port modules provide reliable 1Gbps connectivity via optical or RJ45 interfaces, supporting various transmission distances and network standards.Overview

Huawei offers a range of Gigabit Ethernet (GE) optical and electrical SFP modules designed for self-operated networks, enabling flexible deployment in switches, routers, and access devices. These modules convert optical signals to electrical signals (and vice versa), supporting high-speed data transmission over fiber or copper cabling.
