FTLX8561E2: frequently asked questions
What is the Finisar FTLX8561E2?
The FTLX8561E2 is a Finisar XENPAK transceiver for 10GBASE-SR (XAUI) 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 FTLX8561E2?
The FTLX8561E2 is specified for up to 300m over Duplex MMF SC. Long-reach optics may need an attenuator on short links; we can advise based on your link loss.
Which fiber and connector does the FTLX8561E2 use?
The FTLX8561E2 works at 850nm over Duplex MMF SC. Both ends of a link must use the same optical standard.
Will the FTLX8561E2 work in my Cisco, Juniper, Arista or HPE switch?
The FTLX8561E2 follows the XENPAK 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 FTLX8561E2 rated for?
The FTLX8561E2 is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLX8561E2 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 FTLX8561E2 still available?
The FTLX8561E2 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 FTLX8561E2 price in India and how do I order?
The Finisar FTLX8561E2 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 FTLX8561E2 need?
It runs from 3.3 V, 5 V.
