10G BiDi SFP+ 100km Tx1490/Rx1550 Overview
The BIDI-10G-SFP-100A is a 10G BiDi SFP+ transceiver built for 100km single-fiber SMF links, halving fiber count versus a duplex LR pair. It transmits at 1490nm and receives at 1550nm over a single strand of SMF, with a 25 dB average link budget and full DDM/DOM support. Pair it with the BIDI-10G-SFP-100B (Tx1550nm/Rx1490nm) at the far end to complete the link.

10G BiDi SFP+ 100km Transceiver (Tx1490Rx1550) Description
The BIDI-10G-SFP-100A is a Tx1490nm/Rx1550nm version of the EdgeOptic 10G BiDi SFP+ single-fiber transceiver, built for 100 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 25 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-100A 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-100B as the matching far-end partner for every 100A you install.
The 100 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 2000 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-100A is made to order with a 2-week lead time and ships with a lifetime warranty. For project quantities or to confirm the matching far-end pairing, contact our sales team.
Frequently Asked Questions
Can I use two BIDI-10G-SFP-100A units at both ends of a 100km link?
No. Wavelengths are directional: this unit transmits at 1490 nm and receives at 1550 nm, so the far end must run the complementary BIDI-10G-SFP-100B, which transmits at 1550 nm and receives at 1490 nm. Two BIDI-10G-SFP-100A units cannot link to each other.
Does the far-end module have to be the same brand as the BIDI-10G-SFP-100A?
No. The BIDI-10G-SFP-100A is a standard SFF-8431 SFP+ MSA module, so any transceiver running the mirrored Tx1550nm/Rx1490nm wavelength pair, with a matching 100 km reach and link budget, can sit at the far end. Verify the far-end module's reach and link budget against this unit's specs before deployment.
Can a 10G BiDi SFP+ also run at 1 Gigabit Ethernet?
Yes. Supported data rate spans 1.25 to 11.32 Gbps, and Gigabit Ethernet at 1.25 Gbps is listed alongside 10G Ethernet at 10.31 Gbps in the supported Ethernet applications, so the module works in a Gigabit Ethernet port as well as a 10G port.
