Allied Telesis AT-SP10ER40A/I – TAA 10G SFP+ ER 40km Industrial Temp Transceiver

Product Overview

The Allied Telesis AT-SP10ER40A/I is a TAA-compliant 10G SFP+ extended-reach transceiver rated for industrial operating temperatures from -40°C to +85°C. This is a fiber optic transceiver module, not a switch — it installs into an SFP+ slot on a compatible switch or network adapter to extend a 10 Gigabit Ethernet link over single-mode fiber to 40km using the LC duplex connector and the 10GBase-ER (Extended Reach) standard. The /I suffix denotes industrial temperature rating, distinguishing it from commercial-grade variants with a narrower 0°C to 70°C operating window. TAA (Trade Agreements Act) compliance makes it eligible for U.S. federal government procurement under GSA schedules and other government contracts.

Product Description

The AT-SP10ER40A/I is engineered for long-haul 10G connectivity in environments where commercial-temperature transceivers are unsuitable. The 10GBase-ER specification supports links up to 40km over OS2 single-mode fiber with an LC duplex connector, making it the correct choice for metropolitan area network (MAN) interconnects, utility substation SCADA links, military base backbone connections, and any outdoor or unconditioned-space deployment where temperatures can reach -40°C or +85°C. This distinguishes it from standard 10GBase-ER transceivers, which are rated for 0°C to 70°C commercial environments. It also differs from BiDi (bidirectional) 40km transceivers, which use a single fiber strand and wavelength multiplexing — this module is duplex (two fibers, one Tx and one Rx wavelength on separate strands). TAA compliance is a hard procurement requirement for many federal civilian agencies, DoD contracts, and state government IT departments; the /I variant satisfies both the industrial temperature and TAA requirements in a single SKU. The module is factory-tested and compatible with Allied Telesis switches and the Allied Telesis DNC10 Series 10G PCI-Express network adapters. It plugs into any industry-standard SFP+ cage.

Frequently Asked Questions

Q: What does 10GBase-ER mean and how far does it reach?

10GBase-ER (Extended Reach) is an IEEE 802.3ae standard for 10 Gigabit Ethernet over single-mode fiber at up to 40km. It uses a 1550nm wavelength. For links under 10km, 10GBase-LR is the more common and less expensive choice. For links beyond 40km, DWDM or amplified optics are required.

Q: What is the /I suffix and why does it matter?

The /I suffix designates the industrial temperature variant, rated -40°C to +85°C. The commercial-grade version is rated 0°C to 70°C. For outdoor enclosures, equipment rooms without climate control, or installations in extreme climates, the /I variant is required to prevent transceiver failure.

Q: Is this a BiDi transceiver?

No. This is a standard duplex transceiver using two fiber strands (one for transmit, one for receive). BiDi transceivers use a single fiber strand with wavelength-division multiplexing. Ensure your fiber plant and patch cables match the transceiver type.

Q: What switches are compatible with the AT-SP10ER40A/I?

The AT-SP10ER40A/I installs in any SFP+ slot. It is specifically tested with Allied Telesis switches including the x530 and x530DP series. It is also compatible with the Allied Telesis DNC10 Series 10G PCIe adapters.

Q: Does TAA compliance affect the price or delivery of this transceiver?

TAA compliance means the product is manufactured in a TAA-designated country, making it eligible for U.S. federal government contracts and GSA schedules. It does not impose any functional limitation and is the required version for government procurement.

Q: How does this compare to a 10GBase-ER BiDi 40km module?

A BiDi 40km module uses one fiber strand and is available in paired Tx/Rx wavelengths (e.g., 1270nm/1330nm). This AT-SP10ER40A/I uses two fiber strands at 1550nm. BiDi requires careful wavelength pairing at each end; the duplex ER is simpler to deploy where duplex SMF infrastructure is already in place.

Q: Where can I purchase the AT-SP10ER40A/I?

Order the AT-SP10ER40A/I from creationnetworks.net, an authorized Allied Telesis reseller.
