Import 25g Sfp28 Sr — Buy in wholesale FOB from Supplier in China

Wuhan Fiberhtt Technology Co., Ltd. offers the HSFP8528-SR, a single-rate 25 Gb/s SFP28 optical transceiver designed for short-reach multimode fibre links. The module operates over link distances from 0.5 m to 70 m on OM3 fibre and up to 100 m on OM4 fibre, compliant with IEEE 802.3by 25GBASE-SR optical specifications. It presents a duplex LC optical connection and maintains electrical compatibility with SFP+ 28 Gbps hosts while remaining backward compatible with legacy 10 Gb/s SFP+ pluggable modules.

The HSFP8528-SR integrates transmitter, receiver and control management functions within a single SFP28 package. The 2-wire serial interface handles serial ID, digital diagnostics and module control functions according to standard SFP28 management protocols. The transmitter section typically employs an 850 nm VCSEL paired with a PIN photodiode receiver, though buyers should confirm the exact laser diode and photodetector specifications from Wuhan Fiberhtt. Optical modulation amplitude, extinction ratio and receiver sensitivity must meet IEEE 802.3by clause 112 limits for reliable operation across the stated fibre distances.

This transceiver targets data centre top-of-rack to spine switch links, enterprise server aggregation, and storage area network upgrades where 25 Gb/s lane rates consolidate prior 10 Gb/s infrastructure. The 0.5 m minimum distance supports direct-attach switch-to-switch connections in rack environments. Buyers are typically cloud infrastructure operators, systems integrators and telecom equipment deployers. Pricing, MOQ and exact lead time are not disclosed in the listing and require direct enquiry to Wuhan Fiberhtt. OEM customisation, including private label EEPROM programming and custom heatsink designs, should be discussed with the supplier's engineering team.

Wuhan Fiberhtt Technology Co., Ltd. is situated at Floor 3, Building No. 2, Guan Nan Industrial Park, Optics Valley 1st Road, Wuhan, Hubei Province, China, postal code 430200. The company's location in Wuhan's Optics Valley places it within a recognised cluster of optical communications manufacturing and research. The supplier holds a harbor trust tier, and like its counterpart, shows a response rate of 0.00 percent with zero average response hours on the platform, indicating no recorded buyer engagement through automated messaging channels.

The listing presents a single, precisely identified part number (HSFP8528-SR) with detailed optical and electrical interface specifications. No information is provided about year of establishment, factory floor space, production capacity, employee count, annual revenue, named customers, or quality system certifications such as ISO 9001. Buyers should therefore conduct independent verification of Wuhan Fiberhtt's manufacturing capability, test equipment calibration status, and whether the company operates as a factory or trading intermediary before committing to volume orders.
