QDD-400G-LR4-A-FL Arista (400GBase-LR4) Optical Transceiver
The QDD-400G-LR4-A-FL is a 400Gb/s Quad Small Form Factor Pluggable-double density (QSFP56-DD) optical module designed for 10km optical communication applications. The module converts 8 channels of 50Gb/s (PAM4) electrical input data to 4 channels of CWDM optical signals, and multiplexes them into a single channel for 400Gb/s optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 400Gb/s optical input into 4 channels of CWDM optical signals and converts them to 8 channels of 50Gb/s (PAM4) electrical output data.
The central wavelengths of the 4 CWDM channels are 1271, 1291, 1311 and 1331 nm as members of the CWDM wavelength grid defined in ITU-T G.694.2. The QDD-400G-LR4-A-FL contains a duplex LC connector for the optical interface and a 76-pin connector for the electrical interface. To minimize the optical dispersion in the long-haul system, single-mode fiber (SMF) has to be applied in this module. Host FEC is required to support up to 10km fiber transmission
The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP-DD Multi-Source Agreement (MSA) Type 2. It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.

FluxLight's Full Line of 400GBase-LR4s
Since its inception in 2004, Fluxlight has continually refined its processes to assure the best possible quality for our customers. The foundational elements of these processes are Record-Keeping and Quality Assurance Testing (QAT). To maintain a robust data archive, each part is individually serialized both in its internal EEPROM memory and on its external label. All QAT results and other important information (e.g., manufacture date, compatibility programming) are associated with each Serial Number stored in our cloud-based secure database. QAT consists of visual part inspection as well as verification of all critical parameters and performance of each part. For the QDD-400G-LR4-A-FL optical output power and wavelength are verified on optical spectrum analyzers. Receiver sensitivity is verified at both minimum distance and the 10km maximum range over actual (not simulated) SMF , single-mode fiber cable. Digital Diagnostics Monitoring (DDM) parameters including: optical output power, receive optical power, internal module temperature, transmit bias current and supply voltage, are tested for compliance with specifications. In addition, the part is verified for proper operation across its full operating temperature range, 0C to 50C.
The following is a list of Finisar Corporation patents Fluxlight has licensed. This licensure recognizes and compensates Finisar for their intellectual property. The QDD-400G-LR4-A-FL, like all Fluxlight optical transceivers, is covered by this license agreement. Therefore, Fluxlight customers can rest assured that all products purchased are fully licensed, and our customers are under no potential liability that may ensue from the use of unlicensed optical transceiver products.

Limited Lifetime Warranty
Fluxlight provides a non-transferable serviceable lifetime warranty to the purchaser of Fluxlight hardware product purchased from Fluxlight or an authorized Fluxlight reseller. Fluxlight warrants to the original end customer of its products specified below that its products are free from defects in material and workmanship affecting form, fit, and function. All such products sold will work in the application specified at the time of purchase and will meet the datasheet specifications as found on Fluxlight’s Web site or otherwise provided by Fluxlight. Any claim alleging that any product fails to conform to the foregoing may be made only by the customer who purchased such product and only while such customer owns such product and while the product remains within the serviceable lifetime period. Fluxlight, at its option, will repair, replace, or provide a credit or refund of either the original purchase price or fair market value, whichever is lower, of any product that is determined by Fluxlight to be defective. Some systems that use Fluxlight products may be allowed to operate outside of the system manufacturer’s published settings and Fluxlight does not cover failure in these circumstances. This warranty covers only defects arising under normal use and do not include malfunctions or failures resulting from misuse, abuse, neglect, alteration, problems with electrical power, usage not in accordance with product instructions, acts of nature, or improper installation or improper operation or repairs made by anyone other than Fluxlight or an Fluxlight authorized third-party service provider. Fluxlight reserves the right to substitute functionally equivalent new or serviceable used parts.
