FTLX1841E2: frequently asked questions
What is the Finisar FTLX1841E2?
The FTLX1841E2 is a Finisar X2 transceiver for 10GBASE-ER (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 FTLX1841E2?
The FTLX1841E2 is specified for up to 40km over Duplex SMF 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 FTLX1841E2 use?
The FTLX1841E2 works at 1550nm over Duplex SMF SC. Both ends of a link must use the same optical standard.
Will the FTLX1841E2 work in my Cisco, Juniper, Arista or HPE switch?
The FTLX1841E2 follows the X2 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 does the FTLX1841E2 part number mean?
The FTLX prefix marks Finisar's 10G family (SFP+, XFP, X2, XENPAK). The remaining characters identify the optical design and build variant.
Is the FTLX1841E2 still available?
The FTLX1841E2 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 FTLX1841E2 price in India and how do I order?
The Finisar FTLX1841E2 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.
