Overview
1.25G CWDM SFP optical transceiver is a high-efficiency, wavelength-division multiplexing (WDM) solution designed for cost-effective, high-capacity data transmission in Gigabit Ethernet and Fiber Channel networks. Utilizing Coarse Wavelength Division Multiplexing (CWDM) technology, it operates over a single-mode fiber (SMF) with a transmission distance of up to 20 kilometers, supporting flexible wavelength options (e.g., 1470–1610nm) to optimize fiber resource utilization and network scalability. Ideal for metro access, enterprise backbones, and telecom infrastructure, this LC-interface module enables multiple independent channels over a single fiber, reducing deployment costs and complexity.
Compliant with SFP MSA and IEEE 802.3 standards, it ensures seamless integration with industry-standard equipment. The transceiver features low power consumption, industrial temperature range support (-40°C to 85°C), and digital diagnostics monitoring (DDM/DOM) for real-time performance management. Its hot-swappable design simplifies installation and maintenance, while the compact, rugged build ensures reliability in demanding environments. Combining CWDM’s bandwidth efficiency with SFP flexibility, this module delivers a future-proof, cost-effective solution for expanding optical network capacity and supporting high-density, long-reach applications.
