FTLF8526W4BTL: frequently asked questions
What is the Finisar FTLF8526W4BTL?
The FTLF8526W4BTL is a Finisar SFP+ transceiver for 6.1G CPRI / OBSAI short-wave at 6.1 Gb/s. Finisar is now part of Coherent Corp. (formerly II-VI), and the part number is unchanged. It is used for optical networking.
What is the maximum distance of the FTLF8526W4BTL?
The FTLF8526W4BTL is specified for up to 300 m OM3 over Multimode (OM3). 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 FTLF8526W4BTL?
Per the Finisar family datasheet, the FTLF8526W4BTL transmits −8.2 dBm (Pout) and has a receiver sensitivity of 76 µW OMA. Maximum receiver input is 0 dBm.
Does the FTLF8526W4BTL support DDM / digital diagnostics?
Yes. Digital diagnostics (SFF-8472, A2h). Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTLF8526W4BTL use?
The FTLF8526W4BTL works at 850 nm (840–860 nm) over Multimode (OM3). Both ends of a link must use the same optical standard.
Will the FTLF8526W4BTL work in my Cisco, Juniper, Arista or HPE switch?
The FTLF8526W4BTL follows the SFP+ 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.
What temperature range is the FTLF8526W4BTL rated for?
The FTLF8526W4BTL is an industrial-temperature part rated −40 to 85 °C. Industrial grade suits outdoor cabinets, telecom huts and plant floors.
What does the FTLF8526W4BTL 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 your FTLF8526W4BTL 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 FTLF8526W4BTL price in India and how do I order?
The Finisar FTLF8526W4BTL 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 FTLF8526W4BTL need?
It runs from 3.3 V (3.15–3.46 V) with power dissipation of < 0.5 W.
