Coherent transponder Service Boards

The application of coherent DWDM communication technology in fibre optic infrastructure is one of the most advanced and technologically advanced solutions, offering significant advantages in dispersion control, signal range and other optical properties that significantly improve network performance and efficiency. Transponder and coherent transceiver service boards are widely used in fibre networks to manage and optimise bandwidth utilisation. These devices enable service providers to efficiently use available resources by enabling the transmission of data of different formats over a single fibre infrastructure.

    Coherent optical module 100G CFP (DCO)

    The 100G CFP Coherent Optical Module (DCO) is designed to operate over dual fibre optical cable. On the transmit side, the module converts 25.78 Gbps (CAUI-4) or 27.95 Gbps (OTL4.4) electrical input channels into a single Single Lambda 100G optical signal. The module has a minimum guaranteed optical budget of 18.5 dB, which in most cases is sufficient to reach a distance of 80 km without signal amplification (with signal amplification, the module can reach distances up to 2400 km). The transceiver supports real-time DDM/DOM optical link diagnostics. In addition, it has an in-built generator and Line & Client PRBS checker to help diagnose and test memory status. The module has a dual LC connector facing the line side. On the host side, there is a 148-pin CFP2 MSA compatible connector.

    Product Certification

    Fulfils the requirements of the Low Voltage Directive 2014/35/EU

    Coherent Transponder Service Boards have certificates of conformity to the Low Voltage Directive 2014/35/EU (LVD), which is a “common harmonised safety directive” covering all safety aspects of electrical equipment, not just electrical risks.

    EMC testing ensures that equipment meets EMC standards to minimise the impact of electromagnetic fields on devices and ensure reliable operation in a variety of environments. Passing EMC not only ensures that products meet regulatory requirements, but also identifies and eliminates possible sources of electromagnetic interference that can affect the operation of other devices in the same electromagnetic environment. Compliance with EMC standards contributes to the creation of high-quality products, which ultimately strengthens the competitive position of the DWDM.ME brand as improved performance and reliability of equipment reduces the likelihood of failure in use and increases consumer confidence in the brand.

    Fulfils the requirements of the EMC Directive 2014/30/EU

    The coherent transponder service boards have certificates of conformity to the EMC Directive 2014/30/EU (EMC) for EC technical equipment.

    The directive ensures that equipment designed for use within a certain voltage range is safe for users and complies with European legal requirements.
