10G BiDi SFP+ 80km Transceiver (Tx1490Rx1550) Description
The BIDI-10G-SFP-80A is a Tx1490nm/Rx1550nm version of the EdgeOptic 10G BiDi SFP+ single-fiber transceiver, built for 80 km links over a single strand of single-mode fiber. An EML laser drives the 1490 nm transmit path and an APD photodiode handles the 1550 nm receive path, with an integrated WDM filter separating the two directions on one fiber. The module holds a 23 dB average link budget, 0 to +5 dBm transmit power, and −23 dBm receiver sensitivity with a −7 dBm overload point. Using a single fiber instead of a fiber pair halves the strand count on long-haul spans where dark fiber is scarce or costly.
Built to the SFF-8431 SFP+ MSA, the module drops into any standard SFP+ port and supports broad multi-vendor compatibility through coded EEPROM. Digital diagnostics (DDM/DOM) report real-time temperature, supply voltage, laser bias, transmit power, and received power for link monitoring. The single LC/UPC connector keeps the interface compact, and a +3.3V supply with a 0 to 70 degrees C commercial temperature rating suits standard equipment-room and enclosure deployments.
BiDi modules operate as a complementary pair. The BIDI-10G-SFP-80A transmits at 1490 nm and receives at 1550 nm, so it must be deployed against a Tx1550/Rx1490 unit at the opposite end of the fiber. Two identical Tx1490 modules cannot establish a link, because each module's WDM filter blocks reception of its own transmit wavelength. Order the BIDI-10G-SFP-80B as the matching far-end partner for every 80A you install.
The 80 km reach is ZR-class. Its optical specification derives from the SFF-8431 SFP+ MSA and the STM-64 (OC-192) optical interface rather than IEEE 802.3ae, which tops out at 10GBASE-ER at 40 km. The module carries 10G Ethernet (10.31 Gbps), Gigabit Ethernet (1.25 Gbps), 1G/2G/4G/8G/10G Fibre Channel, and STM-64 SDH/SONET (9.95 Gbps) across the same single-fiber path. Dispersion tolerance is rated at 1600 ps/nm, and the module is CE marked, Class 1 laser-safe to FDA and IEC 60825-1, and RoHS compliant.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms, the BIDI-10G-SFP-80A ships next business day from EU stock with a lifetime warranty. For project quantities or to confirm the matching far-end pairing for your network, contact our sales team.
Frequently Asked Questions
Can I use two BIDI-10G-SFP-80A units at both ends of the link?
No. The BIDI-10G-SFP-80A transmits at 1490 nm and receives at 1550 nm, so two identical units cannot form a link. Pair it with the BIDI-10G-SFP-80B (Tx1550/Rx1490) at the far end of the same single fiber. The complementary wavelengths let each module's WDM filter pass the other's transmit signal.
What single-mode fiber grade should I run for the full 80km reach?
Standard G.652 single-mode fiber (OS2) is the baseline for the rated 80 km span. The module tolerates 1600 ps/nm of chromatic dispersion, which covers a typical G.652 path at this distance. On spans running close to the 80 km limit, G.655 (NZDSF) gives extra dispersion margin. Verify the actual dispersion of your installed fiber against the 1600 ps/nm rating during link planning.
Does the far-end module have to be the same brand as the BIDI-10G-SFP-80A?
No. The BIDI-10G-SFP-80A interoperates with any SFF-8431 MSA-compliant Tx1550/Rx1490 module at the far end, including OEM optics, as long as the wavelength directions are complementary and the reach and link budget match. The wavelength pairing matters far more than the brand on either end.
