FTLX3671DTCxx: frequently asked questions
What is the Finisar FTLX3671DTCxx?
The FTLX3671DTCxx 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 does the 'x' in FTLX3671DTCxx mean?
FTLX3671DTCxx is Finisar's family / ordering name. The 'x' is replaced by a code to make the exact orderable part number. For this family the codes are: 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31 …. Two-digit numbers are ITU / CWDM wavelength channel codes. See the variants table and tell us which one you need, or share your switch and link details and we will pick the right one.
What is the optical power budget of the FTLX3671DTCxx?
Per the Finisar family datasheet, the FTLX3671DTCxx 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 FTLX3671DTCxx 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 part numbers are in the FTLX3671DTCxx family?
Orderable variants include: FTLX3671DTC20, FTLX3671DTC21, FTLX3671DTC22, FTLX3671DTC23, FTLX3671DTC24, FTLX3671DTC25, FTLX3671DTC26, FTLX3671DTC27, FTLX3671DTC28, FTLX3671DTC29, FTLX3671DTC30, FTLX3671DTC31, FTLX3671DTC32, FTLX3671DTC33, FTLX3671DTC34 and 26 more. Next Gen Networks supplies the exact variant you need in bulk with a GST invoice.
What is the maximum distance of the FTLX3671DTCxx?
The FTLX3671DTCxx 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.
Which fiber and connector does the FTLX3671DTCxx use?
The FTLX3671DTCxx works at Channel-specific (see variants) 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 FTLX3671DTCxx work in my Cisco, Juniper, Arista or HPE switch?
The FTLX3671DTCxx 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.
What temperature range is the FTLX3671DTCxx rated for?
The FTLX3671DTCxx is an industrial-temperature part. Industrial grade suits outdoor cabinets, telecom huts and plant floors.
What does the FTLX3671DTCxx 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 FTLX3671DTCxx 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 FTLX3671DTCxx price in India and how do I order?
The Finisar FTLX3671DTCxx 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 FTLX3671DTCxx need?
It runs from 3.3 V (3.14–3.46 V) with power dissipation of 1.6 W max.
