Allied Telesis AT-SP10BD10/I-12 TAA 10G BIDI 10KM LC EXT TEMP -40 TO 85CTAA 10G BIDI 10KM LC 127

Product Overview

The Allied Telesis AT-SP10BD10/I-12 is an industrial-grade 10G BiDi SFP+ transceiver designed for 10km single-fiber links over OS2 single-mode fiber. Transmitting at 1270nm and receiving at 1330nm, this module is the required partner for the AT-SP10BD10/I-13 (1330nm TX) — the two must be deployed as a matched pair at opposite ends of the fiber span to form a complete full-duplex bidirectional 10 Gigabit channel over a single strand of fiber. The industrial I-grade extended temperature rating of -40°C to +85°C makes the AT-SP10BD10/I-12 suitable for outdoor cabinets, transportation infrastructure, utility SCADA networks, and any harsh environment where standard commercial-temperature optics would fail. TAA compliance qualifies this module for US federal and government procurement. Available from Creation Networks at creationnetworks.net.

Product Description

The AT-SP10BD10/I-12 is the 1270nm TX variant of the Allied Telesis SP10BD10/I industrial BiDi SFP+ pair. This module must always be deployed with the AT-SP10BD10/I-13 (1330nm TX) at the far end of the link — the complementary wavelengths (1270nm TX / 1330nm RX on the -12; 1330nm TX / 1270nm RX on the -13) create a full-duplex 10 Gigabit Ethernet channel over a single strand of OS2 single-mode fiber at distances up to 10km. This BiDi single-fiber architecture effectively doubles the bandwidth capacity of existing fiber infrastructure without laying new cable, making it highly cost-effective for enterprise campus uplinks, metropolitan fiber rings, and industrial plant backbones where available fiber strands are limited. The industrial I-grade temperature range of -40°C to +85°C far exceeds the 0°C to 70°C range of commercial-grade optics, qualifying this module for outdoor street cabinets, traffic control systems, railway trackside equipment, utility substations, and government facilities subject to extreme ambient temperatures. Digital Diagnostics Monitoring (DDM) per SFF-8472 provides real-time visibility into TX power, RX power, temperature, supply voltage, and laser bias current via the host switch management interface. The hot-swappable form factor enables field replacement without network downtime, and power consumption is under 1W per module. For longer 40km single-fiber BiDi requirements, the AT-SP10BD40/I series is the appropriate alternative. To order a complete matched pair for a single 10km link, purchase one AT-SP10BD10/I-12 and one AT-SP10BD10/I-13. TAA compliance makes this module eligible for US federal procurement under the Trade Agreements Act.

Frequently Asked Questions

Q: What module must I pair with the AT-SP10BD10/I-12?

The AT-SP10BD10/I-12 (1270nm TX / 1330nm RX) must always be paired with the AT-SP10BD10/I-13 (1330nm TX / 1270nm RX) at the opposite end of the fiber link. Using two identical modules will not produce a working link — the wavelengths must be complementary.

Q: What is the difference between the /I-12 and /I-13 suffixes?

The suffix indicates the TX wavelength: -12 transmits at 1270nm and receives at 1330nm; -13 transmits at 1330nm and receives at 1270nm. One of each is required per fiber span.

Q: How does the AT-SP10BD10/I differ from the AT-SP10BD40/I?

Both are industrial BiDi SFP+ series. The SP10BD10/I reaches up to 10km; the SP10BD40/I reaches up to 40km. For spans beyond 10km, use the SP10BD40/I pair instead.

Q: Can this transceiver be used in a commercial-temperature switch?

Yes. The -40°C to +85°C industrial rating fully encompasses the 0°C to 70°C commercial range. The transceiver can be installed in any SFP+-compatible device regardless of the switch’s own temperature rating.

Q: Is the AT-SP10BD10/I-12 compatible with non-Allied Telesis equipment?

Yes. The module complies with SFP+ MSA standards (SFF-8431, SFF-8472) and is compatible with any switch or router that accepts industry-standard SFP+ modules.

Q: Does this transceiver support digital diagnostics monitoring?

Yes. Full DDM per SFF-8472 is supported, providing real-time visibility into TX power, RX power, temperature, supply voltage, and laser bias current via the switch management interface.
