Finisar compatible FTLX1871D3BNL Description
EdgeOptic's FTLX1871D3BNL 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 FTLX1871D3BNL, 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. Typical deployments are metro and long-haul links over single-mode fiber where the span runs past the 40 km reach of an ER optic.
The original FTLX1871D3BNL is the no-CDR member of the Finisar FTLX1871 series rated for an extended −5 to +85 °C case temperature, which suits outdoor cabinets and industrial enclosures that run hotter than the standard +70 °C ceiling. Like the BCL variant it relies on host-side clock and data recovery for SONET/SDH jitter compliance. The EdgeOptic compatible is built to the 10G-SFP-80 specification with a 0 to 70 °C operating range. For deployments that depend on the extended temperature rating or specific CDR jitter behavior, contact our sales team to confirm the build matches the requirement before ordering.
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 temperature range does the FTLX1871D3BNL support, and how does it differ from the FTLX1871D3BCL?
The original Finisar FTLX1871D3BNL is rated for an extended −5 to +85 °C case temperature, while the FTLX1871D3BCL is rated for a standard −5 to +70 °C range. Both are 1550 nm 80 km 10GBASE-ZR optics with no internal CDR. The extended rating targets outdoor cabinets and industrial enclosures that exceed +70 °C. If your deployment depends on operation above +70 °C, contact our sales team to confirm the EdgeOptic build meets that requirement.
