The LQ-LW100-LR4C is a standards-compliant 100GBASE-LR4 QSFP28 transceiver built for long-reach data center and enterprise interconnects. It combines LAN-WDM technology, 10km transmission capability, and Duplex LC interfaces to deliver efficient and reliable 100G optical connectivity with DDM diagnostics for simplified network operation.
Engineered for optimal fiber efficiency and low power consumption, this reliable 100GBASE-LR4 QSFP28 transceiver provides seamless 103.1Gb/s connectivity up to 10km for demanding networking environments.
The LQ-LW100-LR4C provides 100Gb/s connectivity for high-density data center spine-to-leaf links, where low-latency and stable long-reach optical transmission are essential. It is also well suited for aggregation switches that need dependable 100GBASE-LR4 QSFP28 interoperability across single-mode fiber.
By multiplexing four distinct 25Gb/s optical signals onto a single strand of fiber, this technology dramatically maximizes the bandwidth capacity of existing optical infrastructure. This efficient design eliminates the need to lay expensive additional cables, significantly reducing overall deployment costs for network expansions.
Operating within the highly stable O-band grid, these tightly spaced optical channels effectively minimize chromatic dispersion over standard single-mode fiber links. The precision of the DFB-based transmitter ensures exact wavelength alignment, preventing cross-channel interference and guaranteeing signal integrity.
The LQ-LW100-LR4C is engineered for transmission distances up to 10km on single-mode fiber, making it suitable for campus links, metro-access connections, and inter-rack optical uplinks. This long-reach capability is a key advantage of the 100GBASE-LR4 QSFP28 standard.
The 100GBASE-LR4 QSFP28 module uses a Duplex LC interface, which offers a compact and widely adopted connector type for 100G optical networking. This makes the LQ-LW100-LR4C easier to deploy in existing fiber infrastructure and simplifies integration with standard SMF patch cords.
