We are a proud distributor of the H-MD-04-929-936-SFA and H-MD-04-929-936-SFB, two DWDM filters designed for single-fiber configurations. These filters are designed to utilize eight defined DWDM channels, with each filter using one channel for uplink and another for downlink. This results in a total of 4 bi-directional channels.
These filters are available in two variants, labeled as "A" and "B". The distinction between these two lies in the channels they use for transmission and reception. An additional feature of these filters is an Extension port, which allows for the integration of an extra four channels through the H-MD-04-921-928-SFx filters.
The Extension port operates within the 1460 -1630nm range, making it compatible with OTDR solutions over the same infrastructure. Furthermore, these filters come with a Monitor port that diverts 1% of the transmitted and received line signal. This feature allows for the monitoring of channel power levels via a connected Optical Channel Monitoring (OCM) device or an optical spectrum analyzer.
