The filter type dense wavelength division multiplexer (TFF type DWDM) module achieves low-cost and high reliability multi wavelength multiplexing through thin film filter technology, making it an ideal choice for economical fiber optic communication systems. This module adopts standardized production processes and batch procurement strategies, significantly reducing unit channel costs while maintaining low insertion loss (≤ 1.5dB) and high channel isolation (≥ 35dB). Its compact design (such as 80mm × 60mm × 10mm) further saves installation space and wiring costs, making it particularly suitable for cost sensitive scenarios such as metropolitan area network access and enterprise data center interconnection. It can achieve exponential increase in fiber capacity with a lower budget.

The high-precision TFF DWDM module uses atomic layer deposition (ALD) technology to prepare thin film filters, achieving wavelength control accuracy of ± 0.05nm and meeting the ITU-T G.694.2 standard. Its steep passband edge (≤ 0.5nm transition band) and flat response (≤ 0.5dB fluctuation) effectively suppress adjacent channel crosstalk, supporting high-density deployment with 100GHz/50GHz or even narrower channel spacing. This technology is particularly suitable for scenarios that require ultra-low crosstalk, such as data center interconnection and 5G fronthaul, and maximizes system capacity through precise wavelength management.
The TFF DWDM module designed based on thermal compensation structure has a center wavelength drift of ≤ 0.015nm within a wide temperature range of -40 ℃~+85 ℃. At the same time, through airtight packaging and anti vibration structure design, it ensures long-term stable operation in harsh environments such as outdoor base stations and submarine cables. Its low temperature sensitivity (≤ 0.003nm/℃) and high mechanical strength (impact resistance ≥ 50G) make the module suitable for scenarios with extremely high reliability requirements such as transoceanic communication and military communication. The mean time between failures (MTBF) exceeds 100000 hours, providing solid support for full-service communication networks.
