FTLX8541E2: frequently asked questions
What is the Finisar FTLX8541E2?
The FTLX8541E2 is a Finisar X2 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 FTLX8541E2?
The FTLX8541E2 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.
What is the optical power budget of the FTLX8541E2?
Per the Finisar family datasheet, the FTLX8541E2 transmits −5 to −1 dBm (avg); OMA −2.8 dBm min and has a receiver sensitivity of −11.1 dBm (OMA). Maximum receiver input is −1 dBm.
Does the FTLX8541E2 support DDM / digital diagnostics?
Yes. Digital Optics Monitoring (DOM). Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTLX8541E2 use?
The FTLX8541E2 works at 850nm over Duplex MMF SC. Both ends of a link must use the same optical standard.
Will the FTLX8541E2 work in my Cisco, Juniper, Arista or HPE switch?
The FTLX8541E2 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 temperature range is the FTLX8541E2 rated for?
The FTLX8541E2 is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLX8541E2 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 your FTLX8541E2 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 FTLX8541E2 price in India and how do I order?
The Finisar FTLX8541E2 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 FTLX8541E2 need?
It runs from +5.0 V, +3.3 V, APS +1.2 V with power dissipation of 2.2 W max.
