FTLX6872MNC: frequently asked questions
What is the Finisar FTLX6872MNC?
The FTLX6872MNC is a Finisar SFP+ transceiver for Tunable T-SFP+ 10G-ZR/OC-192, limiting APD 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 FTLX6872MNC?
The FTLX6872MNC is specified for up to 80km 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 FTLX6872MNC?
Per the Finisar family datasheet, the FTLX6872MNC transmits −1 to +3 dBm and has a receiver sensitivity of −24.0 dBm (8.5/9.95G, 1E−12); −23.0 dBm (10.7/11.1G, 1E−12); −27.0 dBm (11.1/11.3G, 1E−4). Maximum receiver input is −7 dBm.
Does the FTLX6872MNC support DDM / digital diagnostics?
Yes. Digital diagnostics via 2-wire serial interface. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTLX6872MNC use?
The FTLX6872MNC works at C-band tunable DWDM 50GHz over Duplex SMF LC. Both ends of a link must use the same optical standard.
Will the FTLX6872MNC work in my Cisco, Juniper, Arista or HPE switch?
The FTLX6872MNC 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.
FTLX6872MNC vs FTLX6871MCC: what is the difference?
Both are in Finisar's FTLX687x family. They differ in temperature grade (extended vs commercial); build / application (Tunable T-SFP+ 10G-ZR/OC-192, limiting APD vs Tunable T-SFP+ 10G-ZR/OC-192, linear APD). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLX6872MNC rated for?
The FTLX6872MNC is an extended-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLX6872MNC 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 FTLX6872MNC 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 FTLX6872MNC price in India and how do I order?
The Finisar FTLX6872MNC 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 FTLX6872MNC need?
It runs from 3.3 V (3.14–3.46 V) with power dissipation of 2.0 W (MCC); 1.8 W typ / 1.9 W max with CDRs on (MNC).
