GLOBALfiber 1.25G CWDM SFP 41dB Industrial Transceiver

Product Overview

The GLOBALfiber 1.25G CWDM SFP 41dB Transceiver is a high-performance single-mode optical transceiver designed for Gigabit Ethernet, Fibre Channel, Metro Ethernet, and industrial fiber optic networks. Featuring an exceptional minimum optical power budget of 41 dB, this module enables ultra-long-distance CWDM transmission over single-mode fiber while maintaining outstanding reliability and stability.

Available in 18 CWDM wavelengths (1270–1610 nm), the module supports passive CWDM networks and is ideal for telecom operators, utilities, industrial automation, and enterprise backbone applications. It incorporates a high-power CWDM DFB laser, an APD receiver, and Digital Diagnostic Monitoring (DDM) for real-time optical performance monitoring.
