ASCENT’s CWDM SFP+ transceivers are designed for use in 10-Gigabit Ethernet links with distances up to 10 km over single-mode fiber. These transceivers include a PIN photo detector diode and uncooled CWDM DFB laser transmitter. Digital diagnostic functions are available via an I2C interface. This module is designed for single-mode fiber and operates at wavelengths between 1270 nm to 1610 nm.
