FTLX2471DC031: frequently asked questions
What is the Finisar FTLX2471DC031?
The FTLX2471DC031 is a Finisar SFP+ transceiver for 10GBASE-LR CWDM, 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 FTLX2471DC031?
The FTLX2471DC031 is specified for up to 10km over Duplex SMF 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 FTLX2471DC031?
Per the Finisar family datasheet, the FTLX2471DC031 transmits −3 to +3 dBm average and has a receiver sensitivity of −12.6 dBm OMA @ 10.5G; stressed −10.3 dBm @ 10.3G. Maximum receiver input is +0.5 dBm.
Does the FTLX2471DC031 support DDM / digital diagnostics?
Yes. SFF-8472 via 2-wire serial interface. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTLX2471DC031 use?
The FTLX2471DC031 works at 1311nm CWDM over Duplex SMF LC. CWDM/DWDM optics must match the channel of your mux/demux port. Both ends of a link must use the same optical standard.
Will the FTLX2471DC031 work in my Cisco, Juniper, Arista or HPE switch?
The FTLX2471DC031 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.
FTLX2471DC031 vs FTLX2471DC027: what is the difference?
Both are in Finisar's FTLX2471 family. They differ in wavelength (1311nm CWDM vs 1271nm CWDM). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLX2471DC031 rated for?
The FTLX2471DC031 is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLX2471DC031 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 FTLX2471DC031 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 FTLX2471DC031 price in India and how do I order?
The Finisar FTLX2471DC031 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 FTLX2471DC031 need?
It runs from 3.3 V (3.14–3.46 V) with power dissipation of < 1 W.
