High-Quality KCO QSFP+ 40G LR4 LC 40Gb/s QSFP+ LR4 SMF 10km LC Transceiver Manufacturer, Product

What is QSFP+ 40G LR4 A 40G QSFP+ LR4 is a hot-pluggable optical transceiver module for 40 Gigabit Ethernet (40GbE) that uses single-mode fiber to transmit data up to 10 kilometers. It operates by combining four separate 10G channels onto two strands of single-mode fiber using CWDM technology, which is then separated back into four 10G channels on the receiving end. This module is known for its high-density connectivity, small form factor.
