StarTech SFP10GLRSTTA Cisco-Compatible 10GBase-LR SFP+ Transceiver Module

Overview

The StarTech SFP10GLRSTTA is a 10GBase-LR small form-factor pluggable transceiver designed as a drop-in compatible replacement for the Cisco SFP-10G-LR-S. It delivers 10 Gbps full-duplex throughput over single-mode fiber at 1310nm with a maximum reach of 10 km (6.2 miles) — making it a practical choice for enterprise campus backbones, data center interconnects, and long-run surveillance network uplinks where you need 10GbE performance without the Cisco OEM price tag. The LC duplex connector and standard SFP+ form factor mean it drops into the same cage and cabling infrastructure you already have in place.

If you're building or extending a network switch infrastructure for a large-scale IP camera deployment, the SFP10GLRSTTA handles the fiber uplink leg between your access-layer PoE switches and core distribution — the segment where bandwidth aggregation matters most.

Key Features

• 10 Gbps Full-Duplex at 10km: Single-mode fiber operation at 1310nm supports runs up to 10 km (6.2 mi) without a repeater. That's enough reach to span most multi-building campuses or connect a remote IDF closet to a central data center on existing OSP fiber — no active equipment in between.
• LC Duplex Connector: Pairs with the LC single-mode fiber patch cords already deployed in most commercial installations. No adapters needed, no retermination required when swapping from a Cisco OEM module.
• Under 1 Watt Power Draw: At less than 1W, this module won't stress your switch's power budget. High-density deployments with 24 or 48 SFP+ ports can fill every cage without thermal derating concerns on the host switch.
• 1,203,430 Hours MTBF: That works out to roughly 137 years of calculated mean time between failures. For infrastructure transceiver slots that nobody wants to touch after installation, that reliability figure matters when you're planning a 10-year infrastructure lifecycle.
• 0°C to 70°C Operating Range: Covers standard commercial and enterprise equipment room environments. This is a commercial-temperature module — not rated for outdoor or industrial enclosures. Plan accordingly if the host switch lives in an unconditioned space.
• Storage Temperature to 85°C: The -40°C to 85°C storage range means safe warehousing in unconditioned environments before installation — a practical consideration for staged rollouts where modules sit in stock for months.
• 5–95% RH Humidity Tolerance: Non-condensing humidity range covers typical data center and wiring closet conditions. Not rated for high-moisture or wash-down environments.
• Compact Form Factor: At 57mm long, 13mm wide, and 10mm tall, weighing just 19 grams, the SFP10GLRSTTA is a standard MSA-compliant transceiver — fits any SFP+ cage with standard ejector latch handling.

Integration and Compatibility

The SFP10GLRSTTA is coded for compatibility with Cisco equipment as a replacement for the SFP+ transceiver modules sold under Cisco part number SFP-10G-LR-S. This matters in Cisco environments where the switch firmware validates transceiver vendor coding before enabling the port — a process called digital optical monitoring (DOM) or vendor lock-in checking. StarTech codes these modules to pass that validation on supported Cisco platforms.

Before deploying in a Cisco Catalyst, Nexus, or ASR platform, confirm your specific switch IOS/NX-OS version and SFP+ slot compatibility with StarTech's compatibility tool or your switch's supported transceiver list. Some Cisco platform revisions or newer IOS versions may display warning messages for third-party transceivers even when the port operates normally — that's a known behavior in Cisco environments and not a functional failure. For guidance on structuring fiber uplinks across a network infrastructure build, consult the network switching buying guide.

This module is also a practical fit for other vendors' SFP+ cages that accept 10GBase-LR MSA-compliant transceivers, though it is marketed and coded specifically for Cisco compatibility.

Frequently Asked Questions

Q: Will the SFP10GLRSTTA work in non-Cisco switches that support 10GBase-LR SFP+ modules?

A: The module follows the MSA 10GBase-LR standard and may function in other vendors' SFP+ cages, but it is specifically coded for Cisco compatibility. Verify with your switch vendor's supported transceiver list before deploying in non-Cisco equipment.

Q: What fiber type and connector does the SFP10GLRSTTA require?

A: It requires single-mode fiber (SMF) with an LC duplex connector. It operates at 1310nm wavelength and supports distances up to 10 km (6.2 miles). It is not compatible with multimode fiber.

Q: Can this module be used in outdoor or industrial enclosures?

A: The SFP10GLRSTTA is rated for 0°C to 70°C operating temperature — a standard commercial temperature range. It is not rated for outdoor or industrial environments. If the host switch is installed in an unconditioned space exceeding 70°C, select an extended-temperature variant instead.

Q: How much power does the SFP10GLRSTTA consume, and does it support dense port deployments?

A: Power consumption is under 1 watt per module. This is low enough that filling a 48-port SFP+ switch with these modules adds less than 48W of transceiver load — a non-issue for most enterprise switch power budgets.

Q: What is the reliability rating of the SFP10GLRSTTA?

A: The published MTBF is 1,203,430 hours — approximately 137 years of calculated mean time between failures. This is a vendor-published figure used for infrastructure lifecycle planning, not a guarantee of individual unit lifespan.

The SFP10GLRSTTA's sub-1W power draw and 1,203,430-hour MTBF are the two numbers I come back to when integrators ask whether third-party transceivers are worth the risk in a long-term infrastructure build. For a fiber uplink module that nobody will touch for years, both figures give you a reasonable confidence baseline — and at 10 km reach on single-mode, this module covers the vast majority of enterprise campus fiber runs without requiring anything exotic.

Technical Highlights:

• 10km Single-Mode Reach: 1310nm wavelength over SMF to 10 km covers most multi-building campus backbones and data center interconnects on existing OSP fiber infrastructure — no repeaters, no amplification required.
• Sub-1W Power Consumption: Under 1 watt per slot means transceiver thermal load is essentially negligible even at full cage density — relevant when you're stacking 48-port SFP+ switches in a tight IDF closet.
• MTBF of 1,203,430 Hours: Roughly 137 years of calculated failure interval. For passive uplink slots in a production network, that's a meaningful lifecycle planning figure — though always maintain a small spare inventory for any high-availability segment.

Deployment Considerations:

• Cisco IOS and NX-OS versions vary in how they handle third-party transceiver coding — some platforms log a warning message even when the port operates normally. Test in your specific platform version before a large-scale rollout.
• The 0°C to 70°C operating range is a hard limit for commercial-temperature modules. If the host switch is in a non-climate-controlled space (rooftop enclosure, warehouse IDF), verify ambient temperature doesn't exceed that ceiling or select an industrial-rated extended-temperature module instead.

The SFP10GLRSTTA is the right call for enterprise wiring closet and data center uplink scenarios where you need proven 10GBase-LR performance in Cisco-compatible hardware, and where transceiver budget — not just port count — is a line item in a large-scale deployment.
