PM DWDM Device

This 12-wavelength MWDM light source for 5G fronthaul serves as a reference light source on production lines for passive optical devices and modules used in the Open-WDM/MWDM 5G fronthaul proposed by China Mobile. It can be combined with an optical power meter, optical switch, and polarization controller to build an automated MWDM module test system. The product delivers stable performance, with short-term power stability of plus or minus 0.005dB. An optional built-in optical switch enables independent remote control of each light-source channel on a millisecond scale. Chassis options include integrated light-source outputs and flexible configurations with a pluggable main unit and modules. The product has an attractive design and a high level of integration.

Our DWDM fiber-spacing matching system is a dedicated instrument developed for practical fiber-device and system applications. Based on our high-resolution optical spectrum analyzer and high-density broadband light-source technologies, it offers spectral resolution up to 0.005nm. As center-wavelength accuracy requirements increase for reliable packaging of fiber devices, modules, and systems, this stable, precise, fast-measuring instrument accurately measures and analyzes the capillary spacing needed for fiber matching. Its unique design provides flexible operation, compact size, integration, and high cost effectiveness, making it an essential tool for passive components in optical communications.

Insertion loss [Full bandwidth]: ≤6.8dB (full bandwidth) Number of Channels: 14 channels Channel Spacing: 100GHz

The L-band polarization-maintaining flat-top AWG has 100GHz channel spacing. Flat-top bandwidth improves wavelength compatibility, with excellent polarization maintenance and high extinction ratio for L-band polarization-sensitive optical communication systems. Miniaturized package.

Insertion loss [ITU passband worst case]: 4.8~5.8dB（ITU 通带最坏情况） Number of Channels: 40 channels (16, 24, 32 channels optional) Channel Spacing: 150GHz

C-band 150GHz polarization-maintaining athermal AWG with 40 channels. Wide spacing improves channel isolation, while excellent polarization maintenance and a compliant extinction ratio support medium- and long-distance polarization-sensitive transmission. It operates over a wide temperature range without temperature control. Datasheet revision: Version 1.0; release date: year 2024, month 12, day 20.

WDM (wavelength-division multiplexing) modules are core wavelength-management components in optical communications. Precision optical design and integration efficiently multiplex and demultiplex multiple wavelengths in one fiber, increasing network capacity and transmission efficiency for 5G/6G communications, data-center interconnects, and backbone networks. High-performance optics support multiple mainstream wavelength bands and simultaneous transmission of tens to hundreds of wavelengths, overcoming single-fiber bandwidth constraints. Low insertion loss and high wavelength isolation reduce energy loss and crosstalk, stabilize transmission, and reduce bit errors. Tengjing Technology's WDM modules serve long-distance, high-capacity backbones, multiservice metropolitan networks, data-center interconnects (DCI), and 5G/6G base-station backhaul. Customized wavelength ranges, port counts, distances, and interfaces, with technical support, improve network performance and meet bandwidth-expansion and efficient-transmission requirements at different scales.
