FTLX3671DTC51: frequently asked questions
What is the Finisar FTLX3671DTC51?
The FTLX3671DTC51 is a Finisar SFP+ transceiver for DWDM fixed 1.2-11.3G multirate 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 FTLX3671DTC51?
The FTLX3671DTC51 is specified for up to 40km 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 FTLX3671DTC51?
Per the Finisar family datasheet, the FTLX3671DTC51 transmits +1 to +4 dBm and has a receiver sensitivity of −16.0 dBm (1.2–10.7G) / −15.0 dBm (11.1–11.3G) at 0 ps/nm; −15.0 / −14.0 dBm at 800 ps/nm. Maximum receiver input is −1 dBm / 0 dBm (two rate−dependent rows).
Does the FTLX3671DTC51 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 FTLX3671DTC51 use?
The FTLX3671DTC51 works at 1536.61nm (ITU C51) 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 FTLX3671DTC51 work in my Cisco, Juniper, Arista or HPE switch?
The FTLX3671DTC51 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.
FTLX3671DTC51 vs FTLX3671DTC20: what is the difference?
Both are in Finisar's FTLX3671DTC family. They differ in wavelength (1536.61nm (ITU C51) vs 1561.42nm (ITU C20)). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLX3671DTC51 rated for?
The FTLX3671DTC51 is an industrial-temperature part. Industrial grade suits outdoor cabinets, telecom huts and plant floors.
What does the FTLX3671DTC51 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 FTLX3671DTC51 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 FTLX3671DTC51 price in India and how do I order?
The Finisar FTLX3671DTC51 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 FTLX3671DTC51 need?
It runs from 3.3 V (3.14–3.46 V) with power dissipation of 1.6 W max.
