Allied Telesis AT-SPBD20LC/I-14 – Industrial BiDi SFP 1G 20km 1490nm
Overview
The Allied Telesis AT-SPBD20LC/I-14 is a TAA-compliant, industrial-grade 1000BASE-BX BiDi SFP transceiver engineered for single-fiber Gigabit Ethernet links up to 20 km over single-mode fiber. Operating on a 1490 nm transmit wavelength, it pairs directly with the AT-SPBD20LC/I-13 (1310 nm TX) to deliver full-duplex bidirectional traffic over a single LC fiber strand. Its extended industrial temperature rating makes it suitable for deployments in environments where commercial-grade optics cannot operate reliably. TAA compliance satisfies federal procurement requirements for government and defense contracts.
Description
The AT-SPBD20LC/I-14 uses wavelength-division multiplexing on a single fiber to simultaneously transmit at 1490 nm and receive at 1310 nm, halving the fiber infrastructure required for point-to-point GbE links. With a reach of 20 km over standard single-mode fiber (SMF), it covers campus inter-building, metro-access, and industrial field-site connections where fiber runs are limited to a single strand.
Rated for operation from -40°C to +85°C, this transceiver is qualified for outdoor enclosures, industrial control networks, transportation infrastructure, and utility SCADA environments. The rugged temperature tolerance eliminates the need for supplemental heating or cooling in harsh field cabinets. The LC duplex connector interface is compatible with all standard LC single-mode fiber patch cables, and the hot-swap capability allows live insertion and removal without powering down the host chassis. This transceiver is compatible with any SFP-compliant switch or router port, including Allied Telesis switches, and requires no driver installation.
TAA (Trade Agreements Act) compliance ensures the AT-SPBD20LC/I-14 meets U.S. federal acquisition requirements, making it appropriate for GSA schedule purchases and DoD network projects. It ships as a single unit and must be paired with the AT-SPBD20LC/I-13 at the far end for bidirectional operation. Available through Creation Networks, a trusted Allied Telesis partner for government, enterprise, and industrial deployments.
Key Features
- Single-Fiber BiDi Operation: Transmits at 1490 nm and receives at 1310 nm over one LC SMF strand, reducing fiber cabling costs by 50%.
- 20 km Reach: Supports Gigabit Ethernet links up to 20 km over standard single-mode fiber without amplification.
- Industrial Temperature Rating: Operates from -40°C to +85°C, suitable for outdoor, transit, utility, and manufacturing environments.
- TAA Compliant: Meets Trade Agreements Act requirements for U.S. federal and government procurement contracts.
- Hot-Swappable: Supports live insertion and removal in any MSA-compliant SFP host device without service interruption.
- Pairs with AT-SPBD20LC/I-13: Designed to operate as a matched pair with the 1310 nm TX variant for full bidirectional links.
- 1000BASE-BX Standard: Complies with IEEE 802.3 1000BASE-BX10 for interoperability with third-party SFP-compliant equipment.
Typical Applications
- Industrial plant and factory floor Gigabit Ethernet fiber backbone links
- Transportation and rail network control systems requiring extended-temperature optics
- Utility and energy SCADA networks with outdoor or uncontrolled-environment cabinets
- Government and defense LAN/WAN fiber extensions requiring TAA-compliant hardware
- Campus or metro-access single-fiber point-to-point GbE connections up to 20 km
- Single-mode fiber infrastructure where only one fiber strand is available per link

FAQ
What is the difference between the AT-SPBD20LC/I-14 and the AT-SPBD20LC/I-13?
The -14 variant transmits at 1490 nm and receives at 1310 nm. The -13 variant transmits at 1310 nm and receives at 1490 nm. One of each model is required at each end of a single-fiber bidirectional link.
Can this transceiver be used with non-Allied Telesis switches?
Yes. The AT-SPBD20LC/I-14 complies with the SFP MSA standard and is compatible with any SFP-compliant switch or router port that supports 1000BASE-BX. Some vendors may require disabling DDM/DOM lock-out features.
What type of fiber cable is required?
Single-mode fiber (SMF) with LC connectors is required. The transceiver is not compatible with multi-mode fiber. Use OS1 or OS2 single-mode patch cables or trunk fiber.
Is this product eligible for U.S. federal government purchase?
Yes. The AT-SPBD20LC/I-14 is TAA compliant, making it eligible for GSA schedule purchases and federal agency procurement under FAR/DFARS requirements.
Does the industrial temperature rating affect installation in standard data centers?
No. The extended temperature range is additive — the transceiver operates normally in standard data center environments (typically 0°C to 70°C) as well as in harsh outdoor or industrial conditions.
Where can I purchase the AT-SPBD20LC/I-14?
