FTEN2217P1CUN-BC: frequently asked questions
What is the Finisar FTEN2217P1CUN-BC?
The FTEN2217P1CUN-BC is a Finisar SFP (SC, single-fiber) transceiver for EPON ONU-on-a-stick PX20+, -BC build at 1 Gb/s. Finisar is now part of Coherent Corp. (formerly II-VI), and the part number is unchanged. It is used for Fast/Gigabit Ethernet, SONET/SDH OC-3/OC-12, campus and access links, and legacy network upgrades.
What is the maximum distance of the FTEN2217P1CUN-BC?
The FTEN2217P1CUN-BC is specified for up to 20km over SMF. 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 FTEN2217P1CUN-BC?
Per the Finisar family datasheet, the FTEN2217P1CUN-BC transmits 0 to +4 dBm and has a receiver sensitivity of −27 dBm. Maximum receiver input is −3 dBm.
Does the FTEN2217P1CUN-BC support DDM / digital diagnostics?
Yes. Built-in digital diagnostics via 2-wire serial bus. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTEN2217P1CUN-BC use?
The FTEN2217P1CUN-BC works at Tx 1310nm / Rx 1490nm (BiDi) over SMF. Both ends of a link must use the same optical standard.
Will the FTEN2217P1CUN-BC work in my Cisco, Juniper, Arista or HPE switch?
The FTEN2217P1CUN-BC 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.
FTEN2217P1CUN-BC vs FTEN2217P1CUN: what is the difference?
Both are in Finisar's FTEN2217P1xUN family. They differ in build / application (EPON ONU-on-a-stick PX20+, -BC build vs EPON ONU-on-a-stick PX20+ (CTC/DPoE OAM)). Pick the variant that matches your temperature, latch and wavelength needs.
What does the FTEN2217P1CUN-BC part number mean?
The FTEN prefix marks Finisar's EPON ONU SFP family. The remaining characters identify the optical design and build variant.
Is your FTEN2217P1CUN-BC 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 FTEN2217P1CUN-BC price in India and how do I order?
The Finisar FTEN2217P1CUN-BC 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 FTEN2217P1CUN-BC need?
It runs from 3.3 V (3.15–3.45 V) with power dissipation of Supply current 500 typ / 620 max mA.
