- Hot-pluggable SFP+ footprint
- Built-in digital diagnostic functions
- 850nm Oxide VCSEL laser transmitter
- 1W maximum power consumption
- Single 3.3V power supply
FTLF8536P5BNL: frequently asked questions
What is the Finisar FTLF8536P5BNL?
The FTLF8536P5BNL is a Finisar SFP28 transceiver for 25GBASE-SR/10G SR-Lite/eCPRI (25GbE only, bail) 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 FTLF8536P5BNL?
The FTLF8536P5BNL is specified for up to 100m (OM4) over MMF. Long-reach optics may need an attenuator on short links; we can advise based on your link loss.
What is the optical power budget of the FTLF8536P5BNL?
Per the Finisar family datasheet, the FTLF8536P5BNL transmits −8.4 to +2.4 dBm avg; OMA ≥ −6.4 dBm and has a receiver sensitivity of −5.2 dBm @25.78G. Maximum receiver input is +2.4 dBm (avg receive range −10.3 to +2.4 dBm).
Does the FTLF8536P5BNL support DDM / digital diagnostics?
Yes. SFF-8472 digital diagnostics, 2-wire. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTLF8536P5BNL use?
The FTLF8536P5BNL works at 850nm over MMF. Both ends of a link must use the same optical standard.
Will the FTLF8536P5BNL work in my Cisco, Juniper, Arista or HPE switch?
The FTLF8536P5BNL 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.
FTLF8536P5BNL vs FTLF8536P5BCL: what is the difference?
Both are in Finisar's FTLF8536P5 family. They differ in temperature grade (extended vs commercial). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLF8536P5BNL rated for?
The FTLF8536P5BNL is an extended-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLF8536P5BNL part number mean?
The FTLF prefix marks Finisar's SFP / SFP28 / SFP56 family (incl. Fibre Channel). The E letter in the suffix usually marks the extended temperature grade. The remaining characters identify the optical design and build variant.
Is your FTLF8536P5BNL genuine Finisar?
Yes. Next Gen Networks supplies original Finisar / Coherent modules, not third-party lookalikes or grey-market stock, and shares serial numbers on request.
What is the FTLF8536P5BNL price in India and how do I order?
The Finisar FTLF8536P5BNL 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 FTLF8536P5BNL need?
It runs from 3.3 V (3.15–3.46 V) with power dissipation of 1 W max (290 mA).
