The GLOBALfiber 8+1 Channel CWDM Mux/Demux (C47-C61 + 1310 nm + Monitor Port, LC, LGX Box) is a premium passive optical module designed to expand fiber capacity in demanding networks. With eight CWDM wavelengths (1470 nm–1610 nm), a dedicated 1310 nm wide-band port for legacy traffic, and built-in monitor port for real-time link supervision, this module is ideal for metro, data-centre, broadcast, finance and cloud back-haul networks where fiber pairs are scarce.
The product features plug-in LGX form-factor, ultra-low insertion loss, high channel isolation, and wide operating temperature range. It enables protocol-transparent transmission of 1G/10G Ethernet, SDH/SONET and higher speeds over a single fiber pair—streamlining deployment and reducing cost.
