Allied Telesis compatible AT-SPBD10-14 Description
EdgeOptic's AT-SPBD10-14 compatible is an Allied Telesis-coded version of the EdgeOptic BiDi-1.25G-SFP-21-BD multi-vendor 1000BASE-BX-D BiDi SFP transceiver. It transmits at 1490 nm and receives at 1310 nm over a single LC/UPC connector, running Gigabit Ethernet on one strand of single-mode fiber instead of two.
Allied Telesis documents the OEM AT-SPBD10-14 as a 1000BASE-BX10 part rated to 10 km. EdgeOptic's compatible is built to the wider BiDi-1.25G-SFP-21-BD design: a DFB transmitter and PIN photodiode receiver with a 15 dB link budget supporting spans to 20 km. Transmit power runs −9 dBm to 3 dBm, with −22 dBm receiver sensitivity and −3 dBm overload; size the actual span loss rather than assuming the OEM's 10 km figure.
Deploy this module opposite an AT-SPBD10-13, which transmits at 1310 nm and receives at 1490 nm, so each direction lands on its own wavelength over the single fiber. Digital diagnostic monitoring follows SFF-8472, and the module carries INF-8074i (SFP MSA), CE, RoHS, and Class 1 FDA and IEC 60825-1 laser safety compliance across a single +3.3V supply and the standard 0°C to 70°C commercial temperature range.
Allied Telesis lists the OEM AT-SPBD10-14 as discontinued; EdgeOptic's compatible remains available as a drop-in replacement built to SFP MSA (INF-8074i) EEPROM conventions. Allied Telesis switches accept third-party SFP modules in standard SFP ports; some stacking-specific ports may require ATI-qualified modules, so confirm port type before deployment.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor platforms, this module ships with a lifetime warranty. For project-quantity pricing or vendor coding, contact our sales team.
Frequently Asked Questions
How is the AT-SPBD10-14 different from the AT-SPBD10-13?
The AT-SPBD10-14 and AT-SPBD10-13 are the two halves of the same BiDi pair and must be deployed opposite one another, never as two of the same part on a single link. Allied Telesis documents the AT-SPBD10-14 as the 1490 nm transmit, 1310 nm receive side; the AT-SPBD10-13 is the opposite side, transmitting at 1310 nm and receiving at 1490 nm. Ordering the same part for both ends of a link results in no link, since both ends would transmit and receive on the same wavelengths.
The OEM AT-SPBD10-14 is rated for 10 km. Why is EdgeOptic's compatible rated for 20 km and 15 dB?
Allied Telesis classifies the OEM AT-SPBD10-14 as a 1000BASE-BX10 part with a 10 km maximum reach. EdgeOptic's compatible module is engineered to the BiDi-1.25G-SFP-21-BD design point, which carries a 15 dB average link budget supporting spans up to 20 km, beyond the OEM's native rating. This is EdgeOptic's own module specification; it does not describe the OEM part's native reach.
Will the AT-SPBD10-14 compatible work in standard Allied Telesis SFP ports?
Allied Telesis switches generally accept third-party transceivers in standard SFP ports. Some stacking-specific ports may require ATI-qualified modules and can reject standard-EEPROM third-party modules, so confirm the port type on the target switch model before deployment.
