TFF Type DWDM Module 500mW CWDM MUX Demux For Dense Fiber Networks
TFF type CWDM module supporting bidirectional communication enhances network capacity
The TFF type CWDM module uses thin film filter technology to transmit multiple optical channels simultaneously in a single fiber through precise wavelength selection and multiplexing functions. This module supports bidirectional communication, which means that upstream and downstream signals can be transmitted in parallel on the same fiber optic cable, significantly increasing network capacity. Its low insertion loss and high channel isolation characteristics ensure stable signal transmission over long distances, making it suitable for scenarios such as data center interconnection, metropolitan area network access points, and 5G fronthaul networks, effectively reducing system operation and maintenance costs.

TFF type CWDM module for high-density wavelength combination and multi-path data transmission
The TFF type CWDM module provides high-density wavelength combinations, supporting 18 wavelength channels (1270 nm~1610 nm), and can achieve multi-path data transmission through flexible configuration. For example, in the scenario of data center interconnection, modules can distribute signals of different wavelengths to multiple servers, achieving parallel transmission and improving network flexibility. Its compact design (80 mm × 60 mm × 10 mm) makes it easy to install in narrow spaces such as rack mounted distribution frames, providing a solution for high-density fiber optic cabling.
TFF type CWDM module with low insertion loss and high bandwidth enhances network performance
The TFF type CWDM module achieves low insertion loss (≤ 1.5 dB) and high bandwidth (covering O, E, S, C, L bands) through thin film filter technology, significantly improving network performance. The low insertion loss characteristic ensures that the signal maintains a high signal-to-noise ratio during long-distance transmission, while the high bandwidth supports multi wavelength parallel transmission, meeting the bandwidth requirements for large-scale network deployment. For example, in 5G fronthaul networks, modules can simultaneously transmit signals of multiple wavelengths, reducing system error rates and improving the reliability of communication links.
TFF type CWDM module for enhancing network anti-interference capability
The TFF type CWDM module effectively suppresses crosstalk between adjacent channels and enhances network anti-interference performance through high channel isolation (≥ 30 dB) and low polarization related loss (≤ 0.1 dB) characteristics. High isolation ensures that signals of different wavelengths do not interfere with each other during transmission, while low polarization related loss ensures the stability of signal transmission. These features enable the module to maintain reliable performance in complex network environments such as metropolitan area network access points, reducing system maintenance costs.
