About the Finisar FTLX1611M3
The Finisar FTLX1611M3 (now a Coherent Corp. product, formerly II-VI) is a XFP 10GBASE-ER / OC-192 IR-2 multirate optical transceiver for 10 Gb/s class links at 1550nm over Duplex SMF LC, with reach up to 40km. 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 bit rates
- Hot-pluggable XFP footprint
- Temperature-stabilized EML transmitter
- Built-in digital diagnostic functions
- RoHS-6 Compliant (lead-free)
FTLX1611M3: frequently asked questions
What is the Finisar FTLX1611M3?
The FTLX1611M3 is a Finisar XFP 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 FTLX1611M3?
The FTLX1611M3 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 FTLX1611M3?
Per the Finisar family datasheet, the FTLX1611M3 transmits −1 to +2 dBm and has a receiver sensitivity of −16 dBm @9.95–10.7 Gb/s. Maximum receiver input is −1 dBm.
Does the FTLX1611M3 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 FTLX1611M3 use?
The FTLX1611M3 works at 1550nm over Duplex SMF LC. Both ends of a link must use the same optical standard.
Will the FTLX1611M3 work in my Cisco, Juniper, Arista or HPE switch?
The FTLX1611M3 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 FTLX1611M3 rated for?
The FTLX1611M3 is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLX1611M3 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 FTLX1611M3 still available?
The FTLX1611M3 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 FTLX1611M3 price in India and how do I order?
The Finisar FTLX1611M3 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 FTLX1611M3 need?
It runs from Vcc5 4.75–5.25 V; Vcc3 3.13–3.45 V; Vcc2 1.71–1.89 V with power dissipation of < 3.5 W.
