Finisar compatible FTLX1871y3BxL Description
EdgeOptic's FTLX1871 series compatible is a Finisar-coded version of the EdgeOptic 10G-SFP-80 multi-vendor 10GBASE-ZR transceiver. It is a 1550 nm SFP+ optic built to drop in for the Finisar FTLX1871 family, carrying multiple vendor codes from a single universal part. The module reaches 80 km over duplex single-mode fiber on a 23 dB link budget.
The transmitter is a 1550 nm cooled EML laser with output between 0 and +5 dBm. The receiver uses an APD photodiode rated to −24 dBm sensitivity, with chromatic dispersion tolerance of 1600 ps/nm. The optic supports a 1.25 to 11.32 Gbps rate range covering 10G Ethernet ZR, Gigabit Ethernet, 1G through 10G Fibre Channel, and SDH STM-64 at 9.95 Gbps. DDM/DOM diagnostics report live temperature, voltage, bias current, and optical power. The module runs on +3.3V and connects through a duplex LC interface.
FTLX1871y3BxL is the notation Finisar uses in its catalog to group the FTLX1871 family rather than a single orderable part number. The orderable Finisar codes are FTLX1871D3BCL, FTLX1871D3BNL, FTLX1871M3BCL, and FTLX1871M3BNL. They divide along two lines: the D3 codes have no internal CDR while the M3 codes carry internal transmitter and receiver CDR for SONET and SDH jitter compliance, and the BCL codes are rated for a standard −5 to +70 °C case temperature while the BNL codes are rated for an extended −5 to +85 °C range. Each of the four concrete SKUs has a dedicated compatible page.
All four variants share the 10GBASE-ZR optical engine. The EdgeOptic compatible is built to the 10G-SFP-80 specification with a 0 to 70 °C operating range. The module is CE marked, Class 1 laser safe per IEC 60825-1 and FDA, RoHS compliant, and built to the SFF-8431 SFP+ MSA. Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty.

Frequently Asked Questions
What does the FTLX1871y3BxL notation cover and which part do I order?
FTLX1871y3BxL is the notation Finisar uses in its catalog to represent the FTLX1871 family as a group, not a single orderable part. The orderable codes are FTLX1871D3BCL and FTLX1871D3BNL (no internal CDR) and FTLX1871M3BCL and FTLX1871M3BNL (internal CDR), where the BCL forms are standard −5 to +70 °C and the BNL forms are extended −5 to +85 °C. Pick the CDR and temperature combination your deployment needs, or contact our sales team to confirm the right variant.
