About the Finisar FTLF1436W4BTL
The Finisar FTLF1436W4BTL (now a Coherent Corp. product, formerly II-VI) is a SFP28 25GE LR / CPRI-eCPRI 24.33G single-rate optical transceiver for 25 Gb/s links at 1310nm over SMF, with reach up to 10km. It is an industrial-temperature part. It belongs to Finisar's FTLF1436W4 family, which has 2 orderable variants that differ by temperature grade, latch, receiver build or wavelength channel. This is a legacy Finisar part; we help buyers find remaining stock or a current Coherent alternative. Typical uses: 25G Ethernet server and leaf links, 5G fronthaul (eCPRI) and 10G-to-25G upgrades.

FTLF1436W4BTL: frequently asked questions
What is the Finisar FTLF1436W4BTL?
The FTLF1436W4BTL is a Finisar SFP28 transceiver for 25GE LR / CPRI-eCPRI 24.33G single-rate 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 FTLF1436W4BTL?
The FTLF1436W4BTL 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 FTLF1436W4BTL use?
The FTLF1436W4BTL works at 1310nm over SMF. Both ends of a link must use the same optical standard.
Will the FTLF1436W4BTL work in my Cisco, Juniper, Arista or HPE switch?
The FTLF1436W4BTL 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.
FTLF1436W4BTL vs FTLF1436W4BTV: what is the difference?
Both are in Finisar's FTLF1436W4 family. They differ in build / application (25GE LR / CPRI-eCPRI 24.33G single-rate vs 25GE LR / CPRI-eCPRI 24.33G dual-rate). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLF1436W4BTL rated for?
The FTLF1436W4BTL is an industrial-temperature part. Industrial grade suits outdoor cabinets, telecom huts and plant floors.
What does the FTLF1436W4BTL part number mean?
The FTLF prefix marks Finisar's SFP / SFP28 / SFP56 family (incl. Fibre Channel). The I letter in the suffix usually marks the industrial temperature grade. The remaining characters identify the optical design and build variant.
Is the FTLF1436W4BTL still available?
The FTLF1436W4BTL is a legacy Finisar part, so new production is limited or ended. Next Gen Networks helps source remaining genuine stock and can suggest a current Coherent alternative with the same reach and wavelength.
What is the FTLF1436W4BTL price in India and how do I order?
The Finisar FTLF1436W4BTL price in India depends on quantity, delivery city and current stock. Next Gen Networks supplies it with a GST invoice (input tax credit ready) and pan-India dispatch from New Delhi. Send the part number, quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in for a GST quote.
What power does the FTLF1436W4BTL need?
It runs from 3.3 V.
