We are a proud distributor of the H-MD-04-921-928-SFA and H-MD-04-921-928-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 come in two variants, labeled as âAâ and âBâ. The distinction between the two lies in the channels used for transmission and reception. An added feature of these filters is an Extension port, which allows for the integration of an additional four channels through the H-MD-04-929-936-SFx filters.
The Extension port operates within the 1460 -1630nm range, making it compatible with OTDR solutions over the same infrastructure. Additionally, these filters come equipped with a Monitor port. This port diverts 1% of the transmitted and received line signal, enabling the monitoring of channel power levels via a connected Optical Channel Monitoring (OCM) device or an optical spectrum analyzer.
