Allied Telesis AT-SP10BD40/I-13 – 10G BiDi SFP+ 40km Industrial 1330nm TX TAA

Product Overview

The Allied Telesis AT-SP10BD40/I-13 is a TAA-compliant Allied Telesis 10G BiDi 40km industrial SFP+ 1330nm transceiver engineered for long-reach single-fiber 10 Gigabit Ethernet links in extreme-environment deployments. Transmitting at 1330nm and receiving at 1270nm over a single LC simplex fiber strand, this 10G BiDi SFP+ 40km single-fiber industrial transceiver maximizes the capacity of existing fiber infrastructure by eliminating the need for a second strand on each link. The extended temperature rating of -40°C to 85°C makes it a leading solution for harsh-environment 10G long-haul SFP+ module applications in transportation, utility, and industrial edge networks.

Product Description

The AT-SP10BD40/I-13 is the complementary pair partner to the AT-SP10BD40/I-12 within the Allied Telesis SP10 Series of industry-standard 10 Gigabit SFP+ modules. This BiDi (Bidirectional) transceiver uses WDM (Wavelength Division Multiplexing) technology to carry transmit and receive traffic on a single optical fiber strand, using 1330nm as the transmit wavelength and 1270nm as the receive wavelength. A working 10G BiDi link requires the AT-SP10BD40/I-13 at one end and the AT-SP10BD40/I-12 at the other end; two units with the same part number cannot be used together as they would transmit and receive on the same wavelength simultaneously. The 40km reach over single-mode fiber enables long-distance campus backbone, MAN, and industrial plant interconnects without optical amplifiers or repeaters. The industrial extended temperature range of -40°C to 85°C allows deployment in outdoor enclosures, trackside cabinets, utility substations, and factory automation environments where commercial transceivers fail. Hot-swap capability allows insertion and removal from the host chassis without service interruption. DDM support per SFF-8472 provides real-time visibility into module health, including transmit and receive optical power, supply voltage, and operating temperature, accessible through the host device's management interface. At under 1 Watt of power consumption, the module imposes minimal thermal burden in densely populated switch or router chassis. TAA compliance and RoHS compliance support both government procurement and environmental sustainability requirements.

Key Features

• Hot-Swappable — Insert or remove from host chassis without taking the link down.
• Digital Diagnostics Monitoring (DDM) — Real-time Tx/Rx power, temperature, and voltage monitoring per SFF-8472.
• Low Power: <1W — Minimal heat contribution in high-density SFP+ deployments.
• MSA Compliant (SFF-8431 / SFF-8472) — Interoperable with any industry-standard SFP+-compatible equipment.
• LC Simplex Connector — Standard LC interface compatible with existing fiber patch panels and structured cabling.
• RoHS Compliant — Meets hazardous substance restrictions for global deployment.

Typical Applications

• Long-haul campus and metropolitan area network backbone links over existing single-mode fiber
• Industrial plant and factory floor interconnects requiring extended temperature tolerance
• Transportation and rail trackside network links in outdoor and harsh-environment cabinets

Frequently Asked Questions

Q: What module must be used at the far end to complete a BiDi link with the AT-SP10BD40/I-13?

The AT-SP10BD40/I-13 must be paired with an AT-SP10BD40/I-12 at the far end. The -13 transmits at 1330nm and receives at 1270nm; the -12 transmits at 1270nm and receives at 1330nm. Two -13 units at both ends will not establish a link.

Q: How does a BiDi transceiver work?

BiDi transceivers use WDM technology to carry both transmit and receive traffic on different wavelengths over a single fiber strand. This halves the fiber count required for each 10G link, effectively doubling the capacity of an existing fiber plant.

Q: What is the maximum reach of the AT-SP10BD40/I-13?

The module supports spans of up to 40km over single-mode fiber, suitable for long-distance campus backbone and metropolitan area network interconnects.

Q: Is the AT-SP10BD40/I-13 compatible with third-party switches and routers?

The module complies with SFP+ MSA standards SFF-8431 and SFF-8472, providing interoperability with any SFP+-compatible equipment meeting these industry standards.

Q: What is the operating temperature range?

The extended-temperature industrial variant is rated from -40°C to 85°C, suitable for outdoor enclosures, trackside cabinets, utility substations, and factory floor deployments.

Q: Is the AT-SP10BD40/I-13 TAA compliant?

Yes. The module is fully TAA compliant and manufactured in Singapore, meeting US federal procurement requirements under the Trade Agreements Act.

Q: Does it support Digital Diagnostics Monitoring?

Yes. DDM is supported per SFF-8472, giving network administrators real-time visibility into transmit and receive optical power, module temperature, and supply voltage.

Q: Where can I buy the AT-SP10BD40/I-13 and its complementary pair?

Both the AT-SP10BD40/I-13 and the complementary AT-SP10BD40/I-12 are available from Creation Networks at creationnetworks.net, an authorized Allied Telesis reseller.
