About the Finisar FTLX8571D3BNL
The Finisar FTLX8571D3BNL (now a Coherent Corp. product, formerly II-VI) is a SFP+ 10GBASE-SR/SW, 10GFC optical transceiver for 10 Gb/s class links at 850nm over Duplex MMF LC, with reach up to 300m OM3. It is an extended-temperature part. It belongs to Finisar's FTLX8571 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: 10G Ethernet, 10G Fibre Channel, SONET OC-192 / OTN and DWDM metro / DCI links.
- Up to 10.5 Gb/s
- Maximum link length of 300 m on 2000 MHz·km MMF
- Uncooled 850 nm VCSEL laser
- Hot-pluggable SFP+ footprint
- Power dissipation < 1 W
- RoHS-6 compliant
FTLX8571D3BNL: frequently asked questions
What is the Finisar FTLX8571D3BNL?
The FTLX8571D3BNL 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 FTLX8571D3BNL?
The FTLX8571D3BNL is specified for up to 300m OM3 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 FTLX8571D3BNL?
Per the Finisar family datasheet, the FTLX8571D3BNL transmits −5 to −1 dBm average launch and has a receiver sensitivity of −11.1 dBm OMA @10.5 Gb/s. Maximum receiver input is +0.5 dBm.
Does the FTLX8571D3BNL 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 FTLX8571D3BNL use?
The FTLX8571D3BNL works at 850nm over Duplex MMF LC. Both ends of a link must use the same optical standard.
Will the FTLX8571D3BNL work in my Cisco, Juniper, Arista or HPE switch?
The FTLX8571D3BNL 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.
FTLX8571D3BNL vs FTLX8571D3BCL: what is the difference?
Both are in Finisar's FTLX8571 family. They differ in temperature grade (extended vs commercial); build / application (10GBASE-SR/SW, 10GFC vs 10GBASE-SR/SW). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLX8571D3BNL rated for?
The FTLX8571D3BNL is an extended-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLX8571D3BNL part number mean?
The FTLX prefix marks Finisar's 10G family (SFP+, XFP, X2, XENPAK). The E letter in the suffix usually marks the extended temperature grade. The remaining characters identify the optical design and build variant.
Is the FTLX8571D3BNL still available?
The FTLX8571D3BNL 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 FTLX8571D3BNL price in India and how do I order?
The Finisar FTLX8571D3BNL 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 FTLX8571D3BNL need?
It runs from 3.3 V (3.14–3.46 V) with power dissipation of < 1 W.
