Import 100g Qsfp28 Lr4 — Buy in wholesale FOB from Supplier in China

The FiberHTT 100G QSFP28 LR4 is a high-speed optical transceiver module designed for long-reach data centre interconnects. It integrates four independent transmitter and receiver lanes into a single compact form factor, with an internal optical multiplexer combining the four transmit channels and a de-multiplexer separating the four receive channels. Each channel is recovered by a PIN photodetector and trans-impedance amplifier before being retimed, ensuring signal integrity across the link. The module fully complies with the QSFP28 Multi-Source Agreement (MSA) and the IEEE 802.3ba standard for 100 Gigabit Ethernet.

This LR4 variant is engineered for single-mode fibre applications, typically supporting reaches of 10 km over duplex LC connectors using four wavelengths around 1310 nm. Each of the four lanes operates at a data rate of 25.78125 Gbps, combining for a total aggregate bandwidth of 100 Gbps. The module draws from a single 3.3V power supply and includes a digital diagnostic monitoring interface compliant with SFF-8472, giving network operators real-time access to parameters such as temperature, voltage, and optical power levels. Standard operating temperature range for telecom-grade LR4 modules is typically 0°C to 70°C.

Buyers sourcing this transceiver are typically data centre operators, telecom carriers, and enterprise network integrators deploying 100G Ethernet links across campus or metro distances. Wuhan Fiberhtt Technology Co., Ltd. manufactures from Wuhan, Hubei Province, a recognised hub for China's photonics industry. Prospective importers should confirm the exact reach specification, connector type, and any carrier-specific compatibility requirements directly with the supplier before placing bulk orders.

Wuhan Fiberhtt Technology Co., Ltd. is based in the Guan Nan Industrial Park on Optics Valley 1st Road in Wuhan, Hubei Province, China. The company operates within the Optics Valley cluster, a region that concentrates a significant share of China's fibre-optic component manufacturing capacity. Its listed address places it in a dedicated industrial park, suggesting access to established supply chain infrastructure for optical components.

The supplier's trust tier is classified as 'harbor' on the platform, though its recorded response rate is currently at 0.00 with no average response time logged. This means prospective buyers have no historical responsiveness data to reference and should factor in potentially longer initial communication cycles. The listing provides detailed technical descriptions of the transceiver architecture, indicating direct manufacturing or close integration with production, but buyers should independently verify production capacity, export licensing, and lead times before committing to volume orders.
