Direct answer for buyers
The XQ+31LC10D is a MikroTik 100G QSFP28 optical module for point-to-point single-mode fibre connections reaching up to 10 kilometres. It is mainly used to connect compatible 100G routing and switching platforms across data-centre rooms, buildings, campuses or metro-style infrastructure. It should be considered by organisations that already have, or plan to deploy, QSFP28-capable equipment and require a long-reach optical path. Before proceeding, confirm the exact host devices at both ends, LC fibre presentation, single-mode cable condition, route length, optical-loss budget, RouterOS version, operating environment and any requirement for redundant links or spare optics.
What the module does
This optical transceiver converts electrical 100 Gigabit Ethernet signals from a supported QSFP28 interface into optical signals that can travel over a pair of single-mode fibres. The module carries traffic through four independent wavelengths, each operating at up to 25 Gbps, and combines them into one 100G connection. That architecture allows network designers to extend high-capacity links well beyond the practical reach of direct-attach copper cables and short-range multimode optics.
The XQ+31LC10D is useful when the network must bridge separate equipment rooms, buildings or infrastructure locations without reducing the backbone to lower-speed uplinks. It does not create switching or routing capacity on its own; the actual throughput, forwarding behaviour, redundancy and management features depend on the MikroTik router or switch receiving the module.
Who it suits
The module may suit internet service providers, hosting environments, data centres, universities, healthcare groups, financial organisations, industrial campuses and larger enterprises that require 100G fibre between compatible systems. It can also be relevant for network integrators building aggregation, core or inter-building links with MikroTik platforms such as selected CCR and CRS devices offering QSFP28 connectivity.
It is not the right choice for a standard SFP, SFP+ or SFP28-only port, for multimode cabling, or for a project whose distance and capacity can be met more economically with a shorter-reach optic or direct-attach cable. FourTeck can help compare practical alternatives after the link route and host equipment are known.
Business challenges this optic can help address
Long fibre routes
When network rooms or buildings are separated by several kilometres, short-reach optics are unsuitable. The XQ+31LC10D provides a 10 km design target over single-mode fibre, subject to the actual optical-loss budget and cabling condition.
Backbone congestion
A 100G uplink can consolidate traffic from multiple access or aggregation layers and reduce the risk that a lower-speed backbone becomes the limiting point. End-to-end performance still depends on switching capacity, configuration and traffic patterns.
Infrastructure expansion
Growing networks often need a path from 10G or 25G access and server links to a higher-capacity core. This module supports a 100G optical interconnect for compatible MikroTik platforms, helping buyers design a clearer upgrade route.
Operational visibility
Digital diagnostic functions can expose operating values such as optical power, temperature, voltage and laser bias current where the host platform supports them, assisting troubleshooting and maintenance planning.

Verified technical information
Compatibility and dependency notice
A QSFP28 optic must be matched to a supported 100G interface. Physical insertion alone does not confirm full compatibility. Buyers should verify the exact router or switch model, RouterOS version, interface capability, supported FEC mode, fibre type, connector presentation and the optic used at the remote endpoint. The optical path should be checked for excessive loss from distance, patch panels, splitters, splices, dirty connectors or tight bends. A module intended for single-mode fibre should not be ordered for a multimode route.
The XQ+31LC10D is designed as a complete 100G optical module. It should not be confused with a breakout cable or a lower-speed SFP28 transceiver. Where the project requires four separate 25G links instead of one 100G optical channel, a different architecture and compatible breakout support may be needed. FourTeck can review the intended topology before the bill of materials is finalised.
A practical purchase and deployment journey
Identify endpoints
Record the exact router or switch at both ends and the QSFP28 port numbers to be used.
Survey the fibre route
Confirm single-mode fibre, route length, LC termination, patching, polarity and estimated optical loss.
Review configuration
Check RouterOS support, interface settings, FEC behaviour, monitoring requirements and redundancy design.
Confirm the bill of materials
Include the required quantity of optics, patch cords, cleaning tools, fibre panels and any spare units.
Test and document
Validate link state, optical readings, throughput expectations and failover, then record the deployed ports and serial details.
Capacity for modern aggregation and core links
A 100G connection is normally considered when several lower-speed links converge on a common switching or routing point. For example, a distribution switch may aggregate multiple 10G or 25G access connections, storage links, server uplinks or customer circuits. Using a 100G optical backbone can provide headroom for that combined traffic and reduce the number of parallel lower-speed uplinks that need to be managed.
The transceiver does not guarantee that every application will achieve 100 Gbps. Real results depend on packet size, host-platform forwarding capacity, routing or bridging configuration, CPU usage, hardware offload, traffic symmetry, congestion and the capabilities of connected systems. Buyers should therefore assess the entire path rather than selecting an optic solely from its headline data rate. FourTeck can help map the module to the intended MikroTik platform and identify whether the surrounding design is capable of using the link effectively.
Capacity planning should also account for growth. A 100G uplink may be justified not only by current traffic but also by the expected addition of servers, virtualisation clusters, backup workloads, cameras, branch connectivity or customer services. At the same time, a project with modest utilisation may be better served by 25G or 40G alternatives. A practical quotation should reflect measured demand, future expansion and the cost of associated fibre components.
Long-reach single-mode fibre design
The 10 km distance rating makes the XQ+31LC10D relevant to inter-building and campus links where short-range modules cannot reach. Distance, however, is only one part of optical design. Every connector, splice and patch panel introduces loss, and fibre condition can change the available margin. The route should therefore be reviewed as an optical system rather than treated as a simple cable length.
Clean connectors are essential at 100G. Dust, damaged ferrules or poor-quality patch cords may prevent the link from establishing or may create intermittent errors. During installation, technicians should inspect and clean LC connectors, maintain correct polarity, avoid sharp bends and document the path. Optical power readings should be compared with the acceptable range for both ends. Where the route approaches the maximum distance or includes many passive connections, professional loss testing is advisable before final commissioning.
Single-mode fibre is normally chosen for longer reach and infrastructure longevity. Buyers should verify the existing cable specification and connector finish rather than assuming that any LC fibre patch lead is suitable. The optic uses a paired-fibre connection, so transmit and receive paths must be correctly crossed between endpoints. FourTeck can assist with patch-cord selection and fibre-path questions when the existing termination information is available.
Diagnostics and operational control
Digital diagnostic monitoring is particularly useful on long-distance links because it can give administrators visibility into optical power, module temperature, supply voltage and laser bias current. These values may help distinguish a fibre problem from a configuration issue or a failing component. They can also support preventive maintenance by highlighting gradual changes in optical levels.
Monitoring is most useful when baseline readings are recorded at commissioning. Network teams can then compare later values after maintenance, cable work or environmental changes. Alerts should be interpreted carefully: a value outside a preferred range may indicate contamination, excess loss, temperature stress or a transceiver issue, but it should be investigated alongside interface errors, link flaps and physical test results.
The precise information displayed depends on the host device and software. Buyers should not assume that every diagnostic field will appear identically on every MikroTik platform or third-party system. Confirming the intended management workflow is part of good procurement, especially for service-provider or data-centre environments where remote troubleshooting is important.
Ideal business environments and use cases
Data-centre interconnect
Connect compatible switches or routers across separate rooms or nearby facilities where a 100G long-reach optical path is required.
Service-provider aggregation
Carry combined subscriber, peering or transport traffic between aggregation and core layers, subject to platform capacity and network design.
Campus backbone
Link buildings across education, healthcare, industrial or corporate campuses using installed single-mode fibre.
High-capacity server networks
Provide an uplink between server-facing 25G access layers and a 100G core where workload and storage traffic justify the capacity.
Network modernisation
Upgrade a constrained backbone while retaining existing single-mode fibre that meets the optical and connector requirements.
Resilient dual-path designs
Deploy paired links across separate routes where business continuity requires redundancy; the routing or switching design must support failover.
Integration and operational considerations
The optic is one component in a complete link. The host device must have a compatible QSFP28 cage and sufficient power, airflow and software support. Network teams should review RouterOS release notes and the MikroTik wired-interface compatibility guidance for the selected platform. Interface behaviour such as auto-negotiation and forward error correction can affect link establishment, particularly when connecting equipment from different vendors.
Both ends should be configured consistently. A mismatch in speed, FEC mode, breakout state or interface profile may leave the physical signal active while preventing reliable traffic. The remote optic should use compatible optical characteristics, connector type and wavelength plan. When a third-party transceiver is installed at the far end, the buyer should confirm interoperability through testing rather than assuming compatibility from the nominal Ethernet standard alone.
Rack design also matters. The module can consume up to 4.5 W and operates within a stated temperature range. High port density can increase local heat around QSFP cages, so airflow should remain unobstructed and the equipment room should stay within the host-device and optic limits. Cable management must avoid tension on LC connectors and tight bends in fibre jumpers.
For critical links, keep commissioning records that include device models, RouterOS versions, port settings, optical readings, fibre route, patch-panel positions and test results. This reduces troubleshooting time and helps future teams understand the installed design.

How FourTeck can assist
FourTeck can help buyers translate a 100G connectivity requirement into a clearer bill of materials. The process can include reviewing the exact MikroTik router or switch, checking whether the selected ports accept QSFP28 modules, confirming the number of links, identifying single-mode patching needs and discussing whether the project requires redundant paths or spare transceivers.
For projects that include deployment services, the quotation can also define fibre inspection, optic installation, interface configuration, FEC review, link testing, optical-value recording and handover documentation. These activities are scope dependent and should be agreed before ordering. Buyers can browse FourTeck technology products, review available network services and support, or send the project requirement for quotation coordination.
An accurate request should include the host equipment, quantity, fibre distance, deployment location and expected schedule. Where the network design is still being developed, FourTeck can discuss suitable alternatives such as shorter-reach optics, direct-attach cables or different MikroTik switching options without assuming that the XQ+31LC10D is the only appropriate component.
