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

The 25G SFP28 optical transceiver from Guangzhou Fiberwdm Electronic Technology Co., Ltd. is a hot-pluggable module designed for 25 Gb/s data rates across three distinct reach configurations. The SR variant supports link lengths up to 100 m over multimode fibre, the LR variant reaches 10 km over single-mode fibre, and the ER variant extends to 40 km over single-mode fibre. All variants conform to the SFP28 mechanical and electrical footprint, enabling direct deployment in switches, routers and storage arrays with native 25 Gb/s ports.

The module employs a standard duplex LC optical interface and operates within commercial temperature ranges typical for data centre environments. Power dissipation and supply voltage parameters align with SFF-8402 and IEEE 802.3by specifications, though buyers should request the exact thermal envelope and current draw from the supplier. The transmitter typically uses a vertical-cavity surface-emitting laser (VCSEL) for SR and cooled distributed-feedback (DFB) or electro-absorption modulated laser (EML) variants for LR and ER respectively. Receiver sections incorporate pin photodiodes with transimpedance amplifiers, with performance contingent on the specific distance grade ordered.

Primary applications include high-speed internet data centre (IDC) spine-leaf interconnects, 5G fronthaul CPRI/eCPRI links, and enterprise campus aggregation where 25 Gb/s lane rates replace legacy 10 Gb/s infrastructure. Buyers are typically system integrators, telecom operators, cloud service providers and large enterprise IT procurement teams. Trade terms, MOQ and lead time are not stated in the listing and must be confirmed directly with Guangzhou Fiberwdm Electronic Technology Co., Ltd. OEM branding and custom firmware compatibility should also be discussed at enquiry stage.

Guangzhou Fiberwdm Electronic Technology Co., Ltd. is located at 241 Commercial Avenue, Huadu District, Guangzhou, Guangdong Province, China, postal code 510800. The company holds a harbor trust tier on the platform, which represents a baseline verification level. The response rate is recorded at 0.00 percent with an average response time of zero hours, indicating that the supplier has not yet established a track record of replying to buyer enquiries through the platform's messaging system.

The supplier's listing focuses on distance-differentiated SFP28 transceivers for data centre and telecommunications applications. No additional profile information discloses year of establishment, registered capital, factory size, employee count, revenue figures, or named client references. Buyers should therefore treat the company as an unverified trading entity until direct due diligence confirms manufacturing capability, quality management system certification, and post-sales technical support capacity.
