6COM 100GE-LR4-QSFP28-20KM 100G Optical Transceiver Module
The 6COM 100GE-LR4-QSFP28-20KM is a high-speed optical transceiver intended for 100 Gigabit Ethernet connectivity over single-mode fiber. Its QSFP28 form factor is designed for compatible high-density switches, routers, and data center networking equipment, supporting long-distance fiber links for enterprise, telecommunications, and data center infrastructure.
The 100G LR4 optical architecture uses four wavelength channels in the 1310nm band, multiplexed over a duplex fiber connection. For a 20km deployment, verify the exact 6COM part number and supported optical specification, as the manufacturer's published 20km product is identified as the QSFP28 LH4 variant.

Installation and Compatibility
Install the transceiver into a compatible QSFP28 interface and connect it to the appropriate single-mode fiber infrastructure. Confirm that both ends of the link support the same optical standard, reach, wavelength plan, and connector type. For a 20km connection, verify that the optical link budget and fiber route meet the module's requirements.
Host-device compatibility should be checked before purchase. Physical fit alone does not guarantee that a transceiver will be accepted by every switch or router; coding and vendor compatibility may vary.
Why Choose a 6COM 100G QSFP28 Transceiver?
A 100G QSFP28 transceiver can help network operators scale bandwidth while retaining a compact, high-density optical interface. For suitable equipment and fiber infrastructure, a long-reach module can support high-capacity links between data centers, aggregation points, and enterprise network locations.
Frequently Asked Questions
1. What is the data rate of this module?
