About the Finisar FTLX3812M331
The Finisar FTLX3812M331 (now a Coherent Corp. product, formerly II-VI) is a XFP DWDM multiprotocol (amplified) optical transceiver for 10 Gb/s class links at 1552.52nm (ITU C31) over Duplex SMF LC. It is a commercial-temperature part. This is a legacy Finisar part; we help buyers find remaining stock or a current Coherent alternative. Typical uses: 10G Ethernet, 10G Fibre Channel, SONET OC-192 / OTN and DWDM metro / DCI links.
- Supports 9.95Gb/s to 11.1Gb/s
- Hot-pluggable XFP footprint
- 100GHz ITU Grid, C-Band
- Temperature-stabilized DWDM EML transmitter
- Power dissipation <3.5W
- Built-in digital diagnostic functions
FTLX3812M331: frequently asked questions
What is the Finisar FTLX3812M331?
The FTLX3812M331 is a Finisar XFP transceiver for DWDM multiprotocol (amplified) 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 FTLX3812M331?
Share your link length and fibre type and we will confirm the reach of the FTLX3812M331 from the Finisar datasheet before you order.
What is the optical power budget of the FTLX3812M331?
Per the Finisar family datasheet, the FTLX3812M331 transmits −3 to +3 dBm (as rendered from FTLX3812M327 spec page; verify). Maximum receiver input is −7 dBm.
Does the FTLX3812M331 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 FTLX3812M331 use?
The FTLX3812M331 works at 1552.52nm (ITU C31) 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 FTLX3812M331 work in my Cisco, Juniper, Arista or HPE switch?
The FTLX3812M331 follows the XFP 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 FTLX3812M331 rated for?
The FTLX3812M331 is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLX3812M331 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 the FTLX3812M331 still available?
The FTLX3812M331 is a legacy Finisar part, so new production is limited or ended. Next Gen Networks helps source remaining genuine stock and can suggest a current Coherent alternative with the same reach and wavelength.
What is the FTLX3812M331 price in India and how do I order?
The Finisar FTLX3812M331 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 FTLX3812M331 need?
It runs from Vcc5 4.75–5.25 V with power dissipation of < 3.5 W.
