Import Cwdm-Sfp — Buy in wholesale FOB from Supplier in China

The CWDM-SFP from Potong Networking Technology Co, Ltd is a compact optical transceiver module built for coarse wavelength division multiplexing applications, supporting data rates up to 1.25 Gbps across fiber networks. It operates at specific CWDM wavelengths (1270 nm to 1610 nm in 20 nm increments) and integrates a 1550 nm DFB laser with a PIN photodetector, delivering reliable bidirectional communication over single-mode fiber. The module complies with IEEE 802.3 and SFF-8472 standards, ensuring interoperability with switches, routers, and other networking equipment from major vendors.

Housed in a standard SFP form factor, this transceiver uses an LC duplex connector interface and supports link lengths of up to 80 km, depending on the chosen wavelength and fiber type. It is designed for industrial operating temperatures ranging from -40°C to 85°C, with low power consumption typically under 1.5W. The CWDM-SFP is RoHS compliant and features digital diagnostics monitoring (DDM) for real-time performance tracking, a standard requirement in telecom and data center deployments.

This module is primarily used in metropolitan area networks, campus backbones, and data center interconnects where cost-effective, scalable bandwidth is required. Telecom operators, ISPs, and enterprise network architects source it for high-density port configurations in access and aggregation layers. Potong Networking Technology Co, Ltd offers the module in bulk with flexible MOQs and supports FOB Shenzhen trade terms, with packaging options including anti-static bags and carton boxes for safe transit.

Potong Networking Technology Co, Ltd is based in Room 2115, Jinfeng Mansion, Futian District, Shenzhen, Guangdong, China, operating as an imported-tier supplier in the optical networking components market. The company specializes in the design and distribution of fiber optic transceivers, including CWDM, DWDM, and SFP modules, catering to telecom and data communication infrastructure providers.

The supplier holds a harbor trust tier, indicating a baseline level of verification, though its response rate is currently recorded at 0.00 with no average response time logged. This suggests that direct engagement may require proactive outreach. The company’s focus remains on delivering optical solutions that meet industry standards, with no additional claims of certifications, client roster, or production scale beyond what is explicitly stated in its profile.
