Yes, the numbers are accurate, since the FMT-plug in card is Low Loss, and the Max. Insertion Loss is 4.8dB. By FS on 03/16/2018

You can use the following method to calculate the compensation length, as a reference to select the DCM you need. The link distance minus the transmission distance of the optical module is the minimum compensation distance, on this basis need to add 20km to ensure enough compensation. For example, if the transmission span is 135km, the compensation length is 75km (135km - 80km + 20km = 75km), which means you can choose a DCM whose compensating length is 80km. By FS on 12/06/2017

Compensated length, utilized position, insertion loss and type of housing need to be comfirmed. By FS on 11/16/2017

Yes, we can provide you a variety of customized products, including different compensation lengths (10km~140km), different technology types(DCF, FBG and Gires-Tournois), different connectors (LC/SC/FC, UPC/APC polish) as well as different types of housing (plug-in card type or 1U 19" rack mount).

Yes, the DCM is passive, you can use it alone. But for the sake of neat and beauty, you had better use the DCM with the FMT 1U Managed Chassis. By FS on 07/20/2017

You need to notice the utilized position of its application, including pre-, link- and post-compensation. But you'd better limit the pre-compensation length winthin 40km, and make sure the link- and post-compensation length don't exceed 100km. By FS on 07/01/2017

Yes, test report and software CD will be attached as well. By FS on 06/18/2017
