从China供应商批量进口10g Base Sr Xenpak Optical Transceiver

The 10G Base SR Xenpak optical transceiver from Shenzhen Poflink Optical Communication Equipment is a short-reach module in the Xenpak form factor, designed for 10 Gigabit Ethernet connections over multimode fibre. It supports a data rate of 10 Gbps and a maximum link distance of 300 metres, operating at an 850 nm wavelength. Xenpak was one of the earliest 10 Gigabit pluggable standards and remains in use across legacy and existing network infrastructure in data centres and enterprise campuses.

The Xenpak form factor is larger than the more recent X2 or SFP+ modules, measuring approximately 121 x 36 x 13 mm, and uses a 70-pin electrical connector. The listing confirms a hot-pluggable design, allowing the module to be replaced without shutting down the host switch or router. Typical Xenpak SR modules support Digital Diagnostic Monitoring (DDM) for real-time tracking of optical power, temperature, and bias current, though buyers should confirm this feature with Shenzhen Poflink for this specific unit.

This transceiver is commonly purchased by network engineers maintaining or expanding existing Xenpak-based switch infrastructure, particularly in environments where upgrading to SFP+ is not yet justified. Applications include inter-switch links in data centres, campus backbone connections, and high-bandwidth video or data transport. Pricing, MOQ, and shipping terms such as FOB Shenzhen or CIF are not specified in the listing and should be confirmed directly with the supplier before ordering.

Shenzhen Poflink Optical Communication Equipment Co., Ltd. operates from 4/F Langfeng Building, Kefa Road, Hi-Tech Industries, Shenzhen 518058, Guangdong, China. The supplier is categorised as an imported-tier seller, and the listing does not include response rate data or average response time. No information is provided about the company's founding date, workforce size, or annual output.

The supplier offers both X2 and Xenpak form factor transceivers for 10 Gigabit networking, suggesting a focus on optical communication components. The product description references ISO and CE certifications, but no certificate details or audit documentation are provided in the listing. Buyers should request verifiable certification records, especially for shipments to markets with strict import compliance requirements such as the European Union or North America.
