Fiberail offers wavelength services via Dense Wavelength Division Multiplexing (DWDM) on its secure and reliable network infrastructure. The wavelength services provide two types of wavelengths- 2.5Gbps and 10Gbps - offering coverage along the fibre cable networks in Peninsular Malaysia.

DWDM, an optical technology used to increase bandwidth over existing backbones, carries multiple protocols and works by combining and transmitting multiple signals simultaneously at different wavelengths on the same fibre.

Fiberail’s wavelength services, can transmit data in Internet Protocol (IP), Synchronous Digital Hierarchy (SDH), Ethernet and Storage Area Network (SAN) - ESCON, FICON, and Fiber Channel - at varying speeds over an optical channel. The Wavelength Services employed over carrier-grade DWDM equipment are supplemented with the following features:

• Full management services -- fault, administration, performance and security management
• Element and network management
• Forward Error Correction (FEC) to improve transmission performance
• Embedded management channels
• Hot-swap technology with in-service upgrades
