About the Finisar FTLB8611P3NC
The Finisar FTLB8611P3NC (now a Coherent Corp. product, formerly II-VI) is a SFP+ BiDi dual-band tunable DWDM T-SFP+ multirate optical transceiver for 10 Gb/s class links at C-band tunable DWDM (dual-band BiDi) over Simplex SMF LC (BiDi), with reach up to 20km. It is an extended-temperature part. It belongs to Finisar's FTLB8611 family, which has 2 orderable variants that differ by temperature grade, latch, receiver build or wavelength channel. Typical uses: 10G Ethernet, 10G Fibre Channel, SONET OC-192 / OTN and DWDM metro / DCI links.
- Hot-pluggable SFP+ footprint
- Self-wavelength tuning with T2DOC and Flextune technologies
- Supports 1.2 to 11.3 Gb/s
- Full C-band tunable with 40 bidirectional Point-to-Point links
- Single LC connector for Bi-directional link
FTLB8611P3NC: frequently asked questions
What is the Finisar FTLB8611P3NC?
The FTLB8611P3NC is a Finisar SFP+ transceiver for BiDi dual-band tunable DWDM T-SFP+ 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 FTLB8611P3NC?
The FTLB8611P3NC is specified for up to 20km over Simplex SMF LC (BiDi). Long-reach optics may need an attenuator on short links; we can advise based on your link loss.
Which fiber and connector does the FTLB8611P3NC use?
The FTLB8611P3NC works at C-band tunable DWDM (dual-band BiDi) over Simplex SMF LC (BiDi). CWDM/DWDM optics must match the channel of your mux/demux port. Both ends of a link must use the same optical standard.
Does the FTLB8611P3NC support DDM / digital diagnostics?
Yes. Digital diagnostics. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Will the FTLB8611P3NC work in my Cisco, Juniper, Arista or HPE switch?
The FTLB8611P3NC 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.
FTLB8611P3NC vs FTLB8611P3CC: what is the difference?
Both are in Finisar's FTLB8611 family. They differ in temperature grade (extended vs commercial). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLB8611P3NC rated for?
The FTLB8611P3NC is an extended-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLB8611P3NC part number mean?
The FTLB prefix marks Finisar's SFP family. The E letter in the suffix usually marks the extended temperature grade. The remaining characters identify the optical design and build variant.
Is your FTLB8611P3NC 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 FTLB8611P3NC price in India and how do I order?
The Finisar FTLB8611P3NC 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 FTLB8611P3NC need?
It runs from 3.3 V.
