Allied Telesis AT-SP10LRM – 10G SFP+ LRM Multimode Transceiver 220m

Product Overview

The Allied Telesis AT-SP10LRM is an Allied Telesis 10G SFP+ LRM multimode transceiver designed for 10 Gigabit Ethernet deployments over legacy multimode fiber infrastructure. Operating at 1310nm, it supports link distances up to 220 meters on OM1 and OM2 multimode fiber, making it well suited for in-building backbone upgrades and data center interconnects where existing fiber plant cannot be replaced. Compatible with all Allied Telesis switches and routers equipped with SFP+ uplink ports, this hot-swappable module installs without downtime. Long-tail search terms include "10GBase-LRM SFP+ 220m OM1 fiber transceiver" and "Allied Telesis SFP+ LRM legacy multimode fiber module".

Product Description

The Allied Telesis AT-SP10LRM delivers 10Gbps data throughput over multimode optical fiber using the 10GBase-LRM standard, with a center wavelength of 1310nm and a maximum reach of 220 meters. This range is specifically designed to support existing OM1 62.5-micron and OM2 50-micron multimode fiber installations that would otherwise be limited to Gigabit speeds, deferring costly fiber replacement projects. The module uses an LC duplex connector and conforms to the SFF-8431 SFP+ Electrical Multi-Source Agreement (MSA), ensuring physical and electrical interoperability with any MSA-compliant SFP+ host. Five digital diagnostic monitoring (DDM) parameters are continuously reported: transceiver temperature, supply voltage (VCC), transmitted optical power, laser bias current, and received optical power — all accessible via standard management interfaces on Allied Telesis platforms. The AT-SP10LRM is hot-swappable, allowing field replacement without powering down the host switch or router, which supports high-availability network architectures. It is RoHS compliant and environmentally certified, meeting requirements for enterprise and government procurement. The module is supported on all Allied Telesis devices with SFP+ ports, including the x530, x550, x930, and SBx908 GEN2 series switches. Power consumption is within standard SFP+ limits, avoiding the need for additional thermal management in dense port configurations.

Frequently Asked Questions

Q: Which Allied Telesis switches are compatible with the AT-SP10LRM?

The AT-SP10LRM is supported on all Allied Telesis switches and routers with SFP+ uplink ports, including the x530, x550, x930, SBx908 GEN2, and other platforms in the Allied Telesis portfolio that accept SFP+ modules.

Q: What fiber type does the AT-SP10LRM require?

The AT-SP10LRM is designed for multimode fiber. It supports OM1 (62.5-micron) and OM2 (50-micron) multimode fiber cables with LC duplex connectors, up to a maximum distance of 220 meters.

Q: Can the AT-SP10LRM be used with single-mode fiber?

No. The AT-SP10LRM is specifically designed for multimode fiber using the 10GBase-LRM standard. For single-mode fiber applications, Allied Telesis offers the AT-SP10LR (10km) and AT-SP10LRA/I series modules.

Q: Is the AT-SP10LRM hot-swappable?

Yes. The AT-SP10LRM can be inserted and removed from a powered SFP+ port without shutting down the host switch, enabling zero-downtime maintenance and replacement.

Q: Does the AT-SP10LRM work with third-party switches?

The AT-SP10LRM complies with the SFF-8431 SFP+ MSA standard, which provides physical and electrical compatibility with MSA-compliant SFP+ ports on equipment from other vendors. However, Allied Telesis only provides support for the module when used in Allied Telesis hardware.

Q: What digital diagnostics does the AT-SP10LRM support?

The module supports five DDM parameters: transceiver temperature, supply voltage (VCC), transmitted optical power, laser bias current, and received optical power. These can be read via the switch management interface on Allied Telesis platforms.

Q: Where can I purchase the AT-SP10LRM?

The AT-SP10LRM is available from Creation Networks at creationnetworks.net, an authorized Allied Telesis reseller providing competitive pricing and expert pre-sales support.
