Specifications
The 10Gbps CWDM SFP+ Transceiver (CT-SFP+CWXX-40) is a high-performance module designed for long-distance optical communication over single-mode fiber (SMF) up to 40 kilometers. It supports data rates up to 11.1Gbps and operates at various CWDM wavelengths, ranging from 1470nm to 1610nm, with a channel spacing of 20nm. The module features a CWDM EML laser and PIN receiver, ensuring reliable signal integrity and compliance with IEEE 802.3ae 10GBASE-ER/EW standards. The transceiver is housed in a compact metal enclosure, which reduces EMI, and includes a duplex LC connector for seamless integration into networking systems.
This module operates on a single +3.3V power supply, with a power consumption of less than 1.5W, and functions reliably within a temperature range of 0°C to 70°C. It is hot-pluggable, compliant with SFF-8472 and SFP+ MSA specifications, and supports advanced digital diagnostic monitoring for real-time access to operational parameters such as temperature, voltage, and optical power. Designed for robust and efficient performance, the CT-SFP+CWXX-40 is an environmentally friendly solution, meeting RoHS compliance standards, and is suitable for Ethernet and telecom applications requiring high-speed, long-distance connectivity.
This CWDM SFP+ transceiver supports up to 11.1 Gbps and complies with IEEE 802.3ae 10GBASE-ER/EW, SFF-8431, and SFF-8472 standards. It operates over a 9/125 µm SMF link up to 40 km, using a duplex LC interface. The module is available in CWDM grid wavelengths (1470, 1490, 1510, 1530, 1550, 1570, 1590, 1610 nm). Power dissipation is <1.5 W with a single 3.3 V supply, and the commercial case operating temperature range is 0 °C to +70 °C. It integrates DDMI for monitoring key parameters.
