FTF3436W5BTV37C: frequently asked questions
What is the Finisar FTF3436W5BTV37C?
The FTF3436W5BTV37C is a Finisar SFP28 transceiver for 25G LR / CPRI-eCPRI CWDM (BT temp code; 'C' suffix as listed) at 25 Gb/s. Finisar is now part of Coherent Corp. (formerly II-VI), and the part number is unchanged. It is used for 25G Ethernet server and leaf links, 5G fronthaul (eCPRI) and 10G-to-25G upgrades.
What is the maximum distance of the FTF3436W5BTV37C?
The FTF3436W5BTV37C is specified for up to 10km over SMF. Long-reach optics may need an attenuator on short links; we can advise based on your link loss.
Which fiber and connector does the FTF3436W5BTV37C use?
The FTF3436W5BTV37C works at 1371nm CWDM over SMF. CWDM/DWDM optics must match the channel of your mux/demux port. Both ends of a link must use the same optical standard.
Will the FTF3436W5BTV37C work in my Cisco, Juniper, Arista or HPE switch?
The FTF3436W5BTV37C follows the SFP28 MSA, so it fits any matching port. It carries Finisar's own EEPROM programming; switches that check the module vendor may need a configuration setting or a vendor-branded optic. Send us your switch model and we confirm before dispatch.
FTF3436W5BTV37C vs FTF3436W5BTV27: what is the difference?
Both are in Finisar's FTF3436W5BTVxx family. They differ in wavelength (1371nm CWDM vs 1271nm CWDM); build / application (25G LR / CPRI-eCPRI CWDM (BT temp code; 'C' suffix as listed) vs 25G LR / CPRI-eCPRI CWDM (BT temp code)). Pick the variant that matches your temperature, latch and wavelength needs.
What does the FTF3436W5BTV37C part number mean?
The FTF3 prefix marks Finisar's 25G CWDM SFP28 family. The remaining characters identify the optical design and build variant.
Is your FTF3436W5BTV37C genuine Finisar?
