Description

The Q-SFP-40G-LR4 is a hot-pluggable QSFP+ optical transceiver designed for 40-Gigabit Ethernet transmission over single-mode fiber. The module converts four 10 Gb/s electrical input channels into four CWDM optical signals, which are multiplexed into a single optical channel for 40 Gb/s transmission. On the receiver side, the optical signal is demultiplexed back into four channels and converted into electrical signals. The module supports transmission distances up to 10 km over single-mode fiber, making it suitable for high-speed network backbone connections.
