10G BiDi SFP+ 80km Transceiver (Tx1550Rx1490) Description
The BIDI-10G-SFP-80B is a Tx1550nm/Rx1490nm 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 1550 nm transmit path and an APD photodiode handles the 1490 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. Running a single fiber instead of a fiber pair frees a strand on long-haul routes where dark fiber is limited or expensive.
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-80B transmits at 1550 nm and receives at 1490 nm, so it must be deployed against a Tx1490/Rx1550 unit at the opposite end of the fiber. Two identical Tx1550 modules cannot establish a link, because each module's WDM filter blocks reception of its own transmit wavelength. Order the BIDI-10G-SFP-80A as the matching far-end partner for every 80B 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-80B 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
Which module pairs with the BIDI-10G-SFP-80B at the far end?
Pair it with the BIDI-10G-SFP-80A (Tx1490/Rx1550). The 80B transmits at 1550 nm and receives at 1490 nm, so the far end must transmit at 1490 nm and receive at 1550 nm. Two 80B units cannot link to each other, since each one's WDM filter blocks reception of its own transmit wavelength. One 80B and one 80A share the same single fiber.
How does the BIDI-10G-SFP-80B map to OEM upstream/downstream (U/D) BX labels?
Match by wavelength, not by the letter. The BIDI-10G-SFP-80B transmits at 1550 nm and receives at 1490 nm. Vendors label the two directions in different ways (U/D, A/B, or by transmit wavelength), and no single IEEE or MSA standard fixes a U or D letter to the 1490/1550 nm pair at 80 km. When cross-referencing an OEM BX part, read its transmit and receive wavelengths from the vendor's transceiver table and pair a 1550 nm transmit module against a 1490 nm transmit module on the same fiber.
Can the far-end module be a different brand than the BIDI-10G-SFP-80B?
Yes. Any SFF-8431 MSA-compliant Tx1490/Rx1550 module works opposite the BIDI-10G-SFP-80B, OEM optics included, provided the wavelength directions are complementary and the reach and link budget line up on both ends. Match the wavelength pairing first; the vendor label on the far end is secondary.
