We propose a scheme of multi-channel quantum random generator based on superluminescent LED (SLED), which can use only one laser source to generate independent random bit sequences parallelly. By using dense wavelength division multiplexing (DWDM) module with 100 GHz interval, we produced 10 random bit streams in different channels, every stream's generating speed reaching 2.5 Gbps. All the random bit sequences can pass the DIEHARD randomness test and NIST-STS test, and there is no apparent correlation between every two bit streams. This multi-channel generator can satisfy the different components' need of random numbers in QKD systems and has advantages in cost of devices.
