FTLX1672M3BNL: frequently asked questions
What is the Finisar FTLX1672M3BNL?
The FTLX1672M3BNL is a Finisar SFP+ transceiver for 10GBASE-ER / OC-192 IR-2 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 FTLX1672M3BNL?
The FTLX1672M3BNL 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 FTLX1672M3BNL?
Per the Finisar family datasheet, the FTLX1672M3BNL transmits −1 to +2 dBm average and has a receiver sensitivity of −16 dBm avg (−14.1 dBm OMA) 3.1–10.7G; −15 dBm avg @ 11.3G; stressed −11.3 dBm OMA @ 10.3G. Maximum receiver input is −1 dBm.
Does the FTLX1672M3BNL 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 FTLX1672M3BNL use?
The FTLX1672M3BNL works at 1550nm over Duplex SMF LC. Both ends of a link must use the same optical standard.
Will the FTLX1672M3BNL work in my Cisco, Juniper, Arista or HPE switch?
The FTLX1672M3BNL 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.
FTLX1672M3BNL vs FTLX1672D3BCL: what is the difference?
Both are in Finisar's FTLX1672 family. They differ in temperature grade (extended vs commercial); build / application (10GBASE-ER / OC-192 IR-2 multirate vs 10GBASE-ER/EW). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLX1672M3BNL rated for?
The FTLX1672M3BNL is an extended-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLX1672M3BNL 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 your FTLX1672M3BNL 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 FTLX1672M3BNL price in India and how do I order?
The Finisar FTLX1672M3BNL 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 FTLX1672M3BNL need?
It runs from 3.3 V (3.14–3.46 V) with power dissipation of 1.5 W.
