Finisar compatible FTLF3436W4BTxx Description

Finisar compatible FTLF3436W4BTxx is SFP28 (Small Form factor Pluggable 28) Transceiver, operating over Double Fiber Single-Mode Fiber (SMF) optical cable. It has minimum guaranteed optical budget of 6.3 dB, with in most cases is enough to reach about 10km distance. 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. This transceiver use top quality DFB Laser transmitter with operating at 1270-1330 nm nominal wavelength (when ordering specific Tx wavelength needs to be selected above) and a 1270-1610 nm PIN photodiode receiver. FTLF3436W4BTxx support DDM/DOM optical diagnostics, that provide diagnostic information about the present operating conditions. Our Finisar compatible SFP28 transceiver operates in Industrial -45°C – +85°C temperature range and has Double LC interface. Finisar compatible FTLF3436W4BTxx support 8.5-28.1 Gbps data rate and such applications as CPRI option 10 (24.33 Gbps), CPRI option 9 (12.165 Gbps), CPRI Option 8 (10.138 Gbps), CPRI option 7 (9.830 Gbps). Our Finisar compatible SFP28 transceiver Double Fiber optical transceiver is multi-purpose module used in number of different places of today's networking. Consequently, most popular applications are Mobile Carrier Networks, thus 5G fronthaul and O-RAN (Open Radio Access Network) applications.

Finisar is one of leading OEM manufacturer in our industry and their products are used by many equipment manufacturers. Our product EEPROM memory will be coded with necessary information to fully meet Finisar compatibility and will work seamlessly with platforms which support Finisar products. Transceiver is also fully compliant to SFP+ MSA, SFF-8402, SFF-8472, SFF-8431, SFF-8432, CE, RoHS-6, Class 1 FDA and IEC60825-1 Laser Safety standard. Transceiver is CE/RoHS certified and is compliant with product safety standards. We'd love to hear about your requirements – Contact Us
