Dell (Force10) compatible 407-BBSK Description

Our Compatible Dell 407-BBSK QSFP+ transceiver is based on our SWDM4-40G-QSFP-350 product, which has the same parameters and is manufactured in accordance with the same industry standards as its OEM counterpart. Our compatible module version is designed for operation over a Double Fiber Multi-Mode Fiber (MMF) optical cable. It has a minimum guaranteed optical budget of 4.5 dB, which typically is enough to reach about 350 meters over OM5 type fiber. However, distance is only an indicative parameter calculated for identification comfort. Finally, we calculate distance while keeping in mind the minimum (guaranteed) optical budget and the average attenuation of optical cabling in the industry. Our Dell 407-BBSK compatible transceiver uses a high-quality VSCEL Laser transmitter operating at 850, 880, 910, 940nm nominal wavelength and a 850, 880, 910, 940nm PIN Photodiode receiver. This module supports DDM/DOM optical diagnostics and provides diagnostic data about the current operating conditions. This compatible module has a Double LC connector and module is designed for operation in standard temperature networking environments ranging from 0°-70°C. The transceiver chipset supports data rates ranging from up to 41.2 Gbps and such applications as 40G Ethernet (41.25Gbps). It is important to note that the mentioned application support will vary depending on the port where the module will be used, and it supported applications as well as module speed configuration during ordering process, but we can ensure that our module will support at least the same functionality as its OEM counterpart. This is a multi-purpose transceiver that can be used in a variety of different places in today's networking. As a result, Internet Service Provider (ISP) Aggregation and Backbone, Mobile Operator Core Networks and Data Center Core Network interconnections are the most popular applications for this product.

Our compatible Dell 407-BBSK module is CE/RoHS certified, it meets product safety standards, and is compliant with QSFP Multi Source Agreement (MSA) SFF-8436 industry standard. To ensure smooth operation, we have completed compatibility tests for this module with the most recent platforms of Dell networking equipment, allowing us to encode transceiver EEPROM memory to be compatible with and work seamlessly in Dell platforms. We are committed to quality, therefore before delivering our products, we conduct stringent quality inspections that include optical parameter measurements, connector cleanliness tests, and EEPROM memory data validation tests. If you have any questions, please Contact us. We will gladly learn about your needs and recommend the best compatible products from our portfolio.
