FTLX8512D3BTL: frequently asked questions
What is the Finisar FTLX8512D3BTL?
The FTLX8512D3BTL is a Finisar XFP transceiver for 10GBASE-SR at 10 Gb/s class. Finisar is now part of Coherent Corp. (formerly II-VI), and the part number is unchanged. It is used for 10G Ethernet, 10G Fibre Channel, SONET OC-192 / OTN and DWDM metro / DCI links.
What is the maximum distance of the FTLX8512D3BTL?
The FTLX8512D3BTL is specified for up to 300m over Duplex MMF LC. 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 FTLX8512D3BTL?
Per the Finisar family datasheet, the FTLX8512D3BTL transmits −5.0 to −1.0 dBm and has a receiver sensitivity of −11.1 dBm @10.5 Gb/s. Maximum receiver input is +0.5 dBm.
Does the FTLX8512D3BTL support DDM / digital diagnostics?
Yes. Built-in digital diagnostic functions. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTLX8512D3BTL use?
The FTLX8512D3BTL works at 850nm over Duplex MMF LC. Both ends of a link must use the same optical standard.
Will the FTLX8512D3BTL work in my Cisco, Juniper, Arista or HPE switch?
The FTLX8512D3BTL follows the XFP 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.
FTLX8512D3BTL vs FTLX8512D3BCL: what is the difference?
Both are in Finisar's FTLX8512 family. They differ in temperature grade (industrial vs commercial). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLX8512D3BTL rated for?
The FTLX8512D3BTL is an industrial-temperature part. Industrial grade suits outdoor cabinets, telecom huts and plant floors.
What does the FTLX8512D3BTL part number mean?
The FTLX prefix marks Finisar's 10G family (SFP+, XFP, X2, XENPAK). The I letter in the suffix usually marks the industrial temperature grade. The remaining characters identify the optical design and build variant.
Is your FTLX8512D3BTL 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 FTLX8512D3BTL price in India and how do I order?
The Finisar FTLX8512D3BTL 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 FTLX8512D3BTL need?
It runs from 3.3 V (3.13–3.45 V) with power dissipation of < 1.5 W.
