5G Fronthaul Semi-active WDM Equipment

Part of the DWDM/CWDM/OTN transmission

The 5G front-haul semi-active wavelength division equipment launched by ISEELINK address the problems of limited optical cable resources, long construction period, and high cost caused by direct drive of optical cables between DU-AAU in 5G front-haul. The DU side uses active WDM equipment, and the AAU side uses a passive wavelength division multiplexer plus colored optical modules to form a unified manageable front-haul network.Supporting IP-based Web management and Netconf/Yang-based unified management for operators, it provides a good solution to help reduce costs, achieve high reliability and quickly deploy 5G front-haul networks.

Product Features

• Huge capacity transmission

Supports 96×400G ultra-large capacity transmissions, that is single fiber transmission capacity up to 38.4Tb/s, and support 80/96×10G/100G/200G/400G hybrid transmission, supporting smooth upgrade from 40 waves to 80 waves, 48 waves to 96 waves. It ensures low investment and smooth expansion in the early stage of network construction to meet the growing bandwidth demand in the future.

• Excellent 400G transmission performance

400G system adopts 16QAM coding technology for coherent detection, supports oFEC, B2B OSNR tolerance index is excellent, adopts industry advanced DSP processing technology, dispersion tolerance is 26000 ps/nm, and supports 400 km or more of non-electric relay transmission. Save investment and greatly facilitate operation and maintenance.

• Flexible and comprehensive service access capability

Supports 100M-100G any service access: CPRI1~10, eCPRI, FE/GE/10GE/25GE/40GE/100GE, FC 1G~32G, STM-N, OTU1/2/3/4, etc. Transparent transmission reduces the cross-transmission delay of the circuit.

• Telecommunications reliable protection

Supports multiple network protection schemes such as optical layer 1+1 channel protection and optical line side 1+1 protection, providing multiple protection for important equipment units and optical fiber lines. Support AC 220V, DC -48V power supply, 1+1 power protection.

• Excellent structure, convenient and easy to maintain

It adopts 1RU, 2RU, 3RU 5RU standard 19-inch rack design, completely configuration-free installation, device plug-and-play, and unified network management platform, providing complete network and equipment performance monitoring capabilities.
