Import Cwdm — Buy in Bulk from Supplier in China

The 155M CWDM from Excom Technology Co. Limited is a coarse wavelength division multiplexer that enables multiple optical signals to transmit simultaneously over a single fiber. It supports up to 16 channels with distinct wavelengths, each designed for telecom-grade performance. The device maintains low insertion loss and high isolation between channels, which is critical for preserving signal integrity in dense network environments.

Built for compatibility with standard single-mode fiber, this CWDM uses industry-recognised 20 nm channel spacing, a typical configuration for metro and access networks. The module integrates passive optical components, with a standard operating temperature range of -5°C to 70°C and a typical insertion loss of <1.5 dB per channel. Its compact 1U rack-mount chassis is designed for easy deployment in telecom racks.

Service providers and data centres use this CWDM for bandwidth expansion without laying additional fiber. It is suited for applications like fiber-to-the-home backbones, enterprise campus networks, and mobile backhaul. Buyers should confirm packaging, which is typically 19-inch rack compatible, and verify compatibility with existing DWDM or optical transport systems. The supplier offers FOB and CIF shipping terms for bulk orders.

Excom Technology Co. Limited is based in Block 101, Shangsha Tech.park, Futian District, Shenzhen, Guangdong, China. The company specialises in optical networking solutions, including multiplexers and fiber optic components for telecom and data centre applications.

The supplier's profile indicates a harbor trust tier, with a listed address in Shenzhen but no recorded response rate or average response time in the available data. Buyers should verify current responsiveness and manufacturing capabilities directly, as the profile does not provide historical performance metrics or certifications beyond the product-level ISO and CE mentions.
