StarTech MASFP1GBLX10 Cisco Meraki-Compatible 1GbE LX SFP Module

Overview

The StarTech MASFP1GBLX10 is a 1000BASE-LX single-mode fiber SFP transceiver engineered to drop into Cisco Meraki switches and routers as a cost-effective alternative to first-party optics. Operating at 1310nm over LC duplex connectors, it delivers full-duplex 1 Gbps throughput across distances up to 10 km — covering inter-building runs, campus backbone links, and remote IDF-to-MDF connections that copper simply cannot reach. With a power draw under 1 W, it won't shift your switch's thermal budget. If you're deploying or expanding a StarTech networking line alongside your Meraki infrastructure, this module fits without proprietary lock-in costs.

Key Features

• 10 km Single-Mode Reach: Spans up to 10 km on standard SMF — enough to connect buildings across a large campus or industrial complex over existing fiber runs without a media converter in the middle. That eliminates a failure point and a power outlet requirement at the midpoint.
• 1310nm Wavelength, Full-Duplex Operation: The 1310nm window is the standard for 1000BASE-LX SMF links per IEEE 802.3z — compatible with the vast majority of installed single-mode plant. Full-duplex at 1.25 Gbps line rate means no half-duplex negotiation penalties on high-throughput trunk ports feeding surveillance recorders or access control servers.
• LC Duplex Connector Interface: LC duplex is the dominant connector type on enterprise-grade patch panels and pre-terminated fiber. If your MDFs and IDFs are already cabled with LC, this module terminates directly without adapter sleeves that introduce additional insertion loss.
• Under 1 W Power Consumption: Drawing less than 1 W, this module is effectively transparent to your switch's PoE or power budget. On a 24- or 48-port Meraki switch where every watt counts against the power supply ceiling, that matters — especially when you're also powering cameras and access control readers off the same chassis.
• MTBF of 3,092,408 Hours: That's roughly 353 years of mean time between failures — a statistical measure, not a guarantee, but it reflects component-grade reliability appropriate for infrastructure links that you don't want to think about after installation. Backbone fiber links are the worst place to have an unplanned outage.
• IEEE 802.3z 1000BASE-LX Compliance: Standards compliance ensures interoperability beyond just Cisco Meraki. If your Meraki switch is replaced, upgraded, or supplemented with another 802.3z-compliant switch, this module works without a forced swap-out.
• 0°C to 70°C Operating Temperature Range: Covers standard indoor data center and IDF closet environments. Not rated for outdoor or unconditioned industrial enclosures — deploy inside a conditioned space. Storage temperature range of -40°C to 85°C means it ships and stores without special handling requirements.
• Compact Form Factor (56.6mm x 13.0mm x 1.2cm): Standard SFP cage footprint at 20g — nothing unusual here, but it confirms you're not dealing with an extended-form module that won't clear adjacent ports in a dense switch stack.

Integration and Compatibility

The MASFP1GBLX10 is coded for Cisco Meraki compatibility, meaning the switch's management software will recognize the module rather than flag it as unsupported. It targets 1 Gbps (1000 Mbps) network environments operating over single-mode fiber, which aligns with standard enterprise uplink configurations for network switches feeding NVRs, VMS servers, and access control panels. For integrators building out fiber-connected surveillance backbones, this module pairs directly with multi-port network video recorders and managed PoE switches on the same uplink fabric. If you're speccing fiber runs for a new site, review our PoE and fiber uplink planning guide to size your backbone correctly before ordering modules. For broader fiber connectivity components, the SFP transceiver category covers complementary wavelengths and reach options.

Frequently Asked Questions

Q: Will the MASFP1GBLX10 trigger an unsupported optic warning on Cisco Meraki switches?

A: The MASFP1GBLX10 is coded for Cisco Meraki compatibility specifically to avoid unsupported optic flags in Meraki's management interface. That said, always verify against your specific Meraki switch model and firmware version before deploying at scale.

Q: What fiber type does the MASFP1GBLX10 require?

A: Single-mode fiber (SMF) with LC duplex connectors. It operates at 1310nm and is rated to 10 km on standard single-mode plant. It is not compatible with multi-mode fiber runs.

Q: What is the maximum link distance for the MASFP1GBLX10?

A: 10 km over single-mode fiber — sufficient for inter-building campus links and most enterprise backbone runs.

Q: How much power does the MASFP1GBLX10 consume?

A: Less than 1 W. It will not meaningfully affect the power budget of any standard enterprise switch chassis.

Q: What is the operating temperature range for the MASFP1GBLX10?

A: 0°C to 70°C operating, -40°C to 85°C storage. It is suitable for conditioned indoor environments such as data centers and IDF closets, but is not rated for outdoor or unconditioned industrial enclosures.

Q: Is the MASFP1GBLX10 a standards-compliant module?

A: Yes. It conforms to IEEE 802.3z 1000BASE-LX, which means it will interoperate with any standards-compliant switch supporting that specification — not exclusively Cisco Meraki hardware.

Karl Wilson

The spec that matters most on the MASFP1GBLX10 is the 10 km single-mode reach combined with a sub-1W power draw — that combination is what makes this module genuinely useful for inter-building surveillance backbones rather than just a budget swap for short-haul uplinks. I've seen integrators reach for multi-mode modules out of habit, then discover their building-to-building runs are SMF. The MASFP1GBLX10 is the right answer for those situations.

Technical Highlights:

• 10 km SMF Reach: Covers virtually any campus or multi-building enterprise layout on a single link — no media converters, no midpoint power requirements, no extra failure points.
• MTBF 3,092,408 Hours: Backbone optics are not the place to cut corners on reliability. A 353-year MTBF rating reflects the component-grade reliability you want on a link that feeds your entire surveillance or access control fabric.
• IEEE 802.3z Compliance: Meraki-coded, but not Meraki-locked. If the switch gets swapped or supplemented, the module stays valid — that's the value of buying to a standard rather than a proprietary spec.

Deployment Considerations:

• Confirm your fiber plant is single-mode before ordering — the MASFP1GBLX10 will not operate on multi-mode runs, and LC connector compatibility does not guarantee SMF compatibility.
• Operating temperature ceiling is 70°C — fine for air-conditioned IDF closets, but not for equipment rooms that run hot in summer or unconditioned utility spaces. Check the ambient before spec'ing.

This module is the right pick for Meraki-managed campus networks where you're connecting buildings over installed single-mode fiber and need a cost-effective, standards-compliant 1GbE uplink that won't generate management alerts or surprise you at the power supply.
