Finisar compatible FTLF3436W5BTVxx Description

Our Compatible Finisar FTLF3436W5BTVxx SFP28 transceiver is based on our CWDM-25G-SFP28-15I-XX 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 Single-Mode Fiber (SMF) optical cable. It has a minimum guaranteed optical budget of 14 dB, which typically is enough to reach about 15 km. 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 Finisar FTLF3436W5BTVxx compatible transceiver uses a high-quality DFB Laser transmitter operating at 1270-1610 nm nominal wavelength and a 1270-1610 nm 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 industrial temperature networking environments ranging from -40° to 85°C. The transceiver chipset supports data rates ranging from 9.8-25.78 Gbps and such applications as 25G Ethernet (25.78Gbps), 10G Ethernet (10.31Gbps). 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) Fiber to the Home Aggregation and Backbone, Mobile Operator Core Networks and Mobile Backhaul and Data Center networking site interconnections are the most popular applications for this product.

Our compatible Finisar FTLF3436W5BTVxx module is CE/RoHS certified, it meets product safety standards, and is compliant with SFP28 Multi Source Agreement (MSA) SFF-8402 industry standard. To ensure smooth operation, we have completed compatibility tests for this module with the most recent platforms of Finisar networking equipment, allowing us to encode transceiver EEPROM memory to be compatible with and work seamlessly in Finisar 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.
