FTLX1371D3BCL: frequently asked questions
What is the Finisar FTLX1371D3BCL?
The FTLX1371D3BCL is a Finisar SFP+ transceiver for 10GBASE-LRM 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 FTLX1371D3BCL?
The FTLX1371D3BCL is specified for up to 220m over Duplex MMF 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 FTLX1371D3BCL?
Per the Finisar family datasheet, the FTLX1371D3BCL transmits −6.5 to +0.5 dBm average and has a receiver sensitivity of −6.0 dBm (comprehensive stressed, symmetrical). Maximum receiver input is +1.5 dBm.
Does the FTLX1371D3BCL support DDM / digital diagnostics?
Yes. SFF-8472 via 2-wire serial interface. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTLX1371D3BCL use?
The FTLX1371D3BCL works at 1310nm over Duplex MMF LC. Both ends of a link must use the same optical standard.
Will the FTLX1371D3BCL work in my Cisco, Juniper, Arista or HPE switch?
The FTLX1371D3BCL 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.
What temperature range is the FTLX1371D3BCL rated for?
The FTLX1371D3BCL is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLX1371D3BCL 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 FTLX1371D3BCL 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 FTLX1371D3BCL price in India and how do I order?
The Finisar FTLX1371D3BCL 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 FTLX1371D3BCL need?
It runs from 3.3 V (3.14–3.46 V) with power dissipation of < 1 W.
