Cost-based optical router DML
DML-based optical modules typically range from €90 to several hundred euros, depending on speed and distance, but exact router pricing varies by vendor and model.
DML (Directly Modulated Laser) technology is commonly used in optical transceivers for routers and switches, particularly in QSFP28 and SFP+ modules. For example, a Nokia QSFP-100G-CWDM4 DML transceiver suitable for 2 km links is priced around €93 . Higher-speed modules, such as 200G QSFP-DD PSM8 DML transceivers, are used for medium to long-distance data center interconnections, with prices typically higher due to increased bandwidth and complexity . For longer distances or specialized applications, modules like 100GBASE-LR4 with DFB lasers can support up to 10 km and are priced higher, reflecting their extended reach and monitoring capabilities . Since the exact price of a Ukrainian optical router with DML is not publicly listed, the cost will depend on the router model, port count, and vendor. Typically, routers incorporating DML transceivers are sold as part of enterprise or carrier-grade networking solutions, and pricing often requires direct inquiry with distributors or manufacturers. Datasheets and technical specifications can be found online to compare compatible modules and features . In summary, while individual DML transceivers can cost from €90 to several hundred euros, the full optical router price will vary significantly based on configuration, vendor, and included features. Contacting suppliers or checking regional distributors is recommended for precise pricing.
