About the Finisar FTLX3613M344
The Finisar FTLX3613M344 (now a Coherent Corp. product, formerly II-VI) is a XFP DWDM multirate 40km optical transceiver for 10 Gb/s class links at 1542.14nm (ITU C44) over Duplex SMF LC, with reach up to 40km. It is a commercial-temperature part. It belongs to Finisar's FTLX3613 family, which has 46 orderable variants that differ by temperature grade, latch, receiver build or wavelength channel. 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 11.32Gb/s bit rates
- 100GHz channel spacing on the ITU C-band
- Hot-pluggable XFP footprint
- Temperature-stabilized 1550nm EML transmitter
- Supports -300ps/nm to +800ps/nm
- RoHS-6 Compliant (lead-free)
FTLX3613M344: frequently asked questions
What is the Finisar FTLX3613M344?
The FTLX3613M344 is a Finisar XFP transceiver for DWDM multirate 40km 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 FTLX3613M344?
The FTLX3613M344 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 FTLX3613M344?
Per the Finisar family datasheet, the FTLX3613M344 transmits −1 to +2 dBm and has a receiver sensitivity of −16 dBm (<10.7 Gb/s); −15 dBm (>11.05 Gb/s). Maximum receiver input is −1 dBm.
Does the FTLX3613M344 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 FTLX3613M344 use?
The FTLX3613M344 works at 1542.14nm (ITU C44) 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 FTLX3613M344 work in my Cisco, Juniper, Arista or HPE switch?
The FTLX3613M344 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.
FTLX3613M344 vs FTLX3613M316: what is the difference?
Both are in Finisar's FTLX3613 family. They differ in wavelength (1542.14nm (ITU C44) vs 1564.68nm (ITU C16)). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLX3613M344 rated for?
The FTLX3613M344 is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLX3613M344 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 FTLX3613M344 still available?
The FTLX3613M344 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 FTLX3613M344 price in India and how do I order?
The Finisar FTLX3613M344 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 FTLX3613M344 need?
It runs from 3.3 V (3.13–3.45 V) and 5 V (4.75–5.25 V) with power dissipation of < 3.5 W.
