# Product Documentation
# Product Description

    SWDM4-40G-QSFP-350 is Multi-Vendor MSA Compatible QSFP (Quad Small Form-factor Pluggable) Transceiver, operating over pair of Multi-Mode optical fiber providing four independent optical communication lanes separated from each other using SWDM4 technology. Module has minimum guaranteed optical budget of 4.5 dB, which in most cases is enough to reach 240 meters (OM3) and 350 meters (OM4) cable. However, distance is just indicative parameter calculated for comfort of identification. Eventually we calculate distance taking in account minimal optical budget and average attenuation of optical cabling in industry. SWDM4-40G-QSFP-350 uses 4 x VCSEL transmitting lasers and 4 x PIN receivers, operating each lane with speeds of 10.31 Gbps, giving an aggregated maximum bandwidth of 41.2 Gbps. Module supports DDM/DOM optical diagnostics, which provide diagnostic information about the present operating conditions. SWDM4-40G-QSFP-350 operates in Standard 0°-70°C temperature range and has double LC connector. SWDM4-40G-QSFP-350 support 41.2 Gbps data rate and such applications as 40G Ethernet (41.2 Gbps). SWDM4-40G-QSFP-350 optical transceiver is multi-purpose module used in number of different places of today’s networking. Consequently, most popular applications are Internet Service Provider (ISP) Fiber To The Home aggregation and backbone, Mobile operator core and back-haul 40G applications, Data Center networking site interconnections and other optical links.

    Transceiver is CE/RoHS certified and it is Compliant with product safety standards. SWDM4-40G-QSFP-350 Transceiver is fully compliant to QSFP+ Multi Source Agreement. Consequently, it means that module is compatible with 80% of networking equipment, where is not implemented a special algorithm for protection against third party modules. However – we can provide QSFP+ transceiver with custom-encoded firmware in order to make it work almost in any equipment. Therefore, we will be glad to know what your requirement is. Because our focus is providing top quality service, we are performing serious quality checks before delivery of our products. As a result, we do optical parameter measurements, connector cleanness tests and QSFP+ transceiver EEPROM memory data validation tests – Contact us
