FTLX8574D3BCL: frequently asked questions
What is the Finisar FTLX8574D3BCL?
The FTLX8574D3BCL is a Finisar SFP+ transceiver for 10GBASE-SR/SW, 10GFC 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 FTLX8574D3BCL?
The FTLX8574D3BCL is specified for up to 300m OM3/400m OM4 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 FTLX8574D3BCL?
Per the Finisar family datasheet, the FTLX8574D3BCL transmits −5 to −1 dBm average launch (OMA ≥ −1.5 dBm) and has a receiver sensitivity of −11.1 dBm unstressed OMA; −7.5 dBm stressed OMA @10.3 Gb/s. Maximum receiver input is +0.5 dBm.
Does the FTLX8574D3BCL support DDM / digital diagnostics?
Yes. Digital diagnostics per SFF-8472, 2-wire serial. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTLX8574D3BCL use?
The FTLX8574D3BCL works at 850nm over Duplex MMF LC. Both ends of a link must use the same optical standard.
Will the FTLX8574D3BCL work in my Cisco, Juniper, Arista or HPE switch?
The FTLX8574D3BCL 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.
FTLX8574D3BCL vs FTLX8574D3BNL: what is the difference?
Both are in Finisar's FTLX8574 family. They differ in temperature grade (commercial vs extended). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLX8574D3BCL rated for?
The FTLX8574D3BCL is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLX8574D3BCL part number mean?
The FTLX prefix marks Finisar's 10G family (SFP+, XFP, X2, XENPAK). The C letter in the suffix usually marks the commercial temperature grade. The remaining characters identify the optical design and build variant.
Is your FTLX8574D3BCL 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 FTLX8574D3BCL price in India and how do I order?
The Finisar FTLX8574D3BCL 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 FTLX8574D3BCL need?
It runs from 3.3 V (3.14–3.46 V) with power dissipation of < 1 W.
