100G and 200G Optical Transceivers Product Detail
100G QSFP28 LR4 is a QSFP28 LR4 option using Duplex LC for 10km single-mode fiber links.
Use the published model direction and key parameters for selection and sample planning. Confirm compatibility coding, optional temperature grade, and production parameters in the formal specification or order document.

100G QSFP28 LR4 is designed for 10km links using Duplex LC. Selection must confirm the host form factor, electrical interface, PMD, FEC, fiber mapping, power and thermal limits, software version and the remote endpoint; the model name alone does not establish interoperability.
Selection FAQ
100G QSFP28 LR4 is listed for 10km over duplex single-mode fiber on Duplex LC. What decides it on site is the total loss budget: fiber attenuation plus every connector, splice and patch panel in the path. Measure the installed link rather than trusting the reach label.
Often yes. 100G QSFP28 LR4 is built to drive 10km, so on a few metres of fiber the received power can exceed the receiver overload point, which shows up as errors or a link that will not stay up. Check the overload figure in the ordering specification and attenuate the bench setup accordingly.
Give the host vendor, model and software version at both ends, the QSFP28 port or lane mode, the operating temperature range, the quantity per site and the target delivery date. For 100G QSFP28 LR4 also state the measured link distance, fiber attenuation and the number of connectors and splices in the path. Compatibility is confirmed per platform, so the host details matter as much as the optical specification.
