FAQ
Why does this kit include two different transceivers?
The S-35LC20D and S-53LC20D use complementary transmit and receive wavelengths so a single fiber strand can carry traffic in both directions over one link.
What is the maximum reach of this module pair?
Each transceiver supports single mode fiber connections up to 20 kilometers with DDM diagnostics for link monitoring.

Frequently Asked Questions
Why deploy a matched pair of transceivers with complementary wavelengths?
Using 1310nm and 1550nm on opposite ends enables bidirectional communication over a single fiber strand via wavelength division multiplexing (WDM), effectively doubling fiber utilization and reducing installation costs.
Can the S-35LC20D and S-53LC20D pair work over any single-mode fiber?
Yes; both operate at 1.25 Gbps on standard single-mode fiber up to 20 kilometers, making them universally compatible with existing telecom or campus fiber backbones.
What is the practical throughput over 20-kilometer single-mode links?
With proper fiber quality and connection, you should achieve close to the full 1.25 Gbps in each direction simultaneously, suitable for voice, video, and moderate data traffic between remote sites.
Does DDM diagnostics help troubleshoot fiber optic problems?
Yes; DDM real-time monitoring of signal strength, temperature, and voltage helps identify marginal connections or failing modules before they cause network outages.
Can we expand this 20km link using repeaters or amplifiers?
Yes; for distances beyond 20km, optical repeaters or amplifiers can extend the link, though this adds cost and complexity. Contact Procure.ae to assess whether upgrades suit your topology.
Is this pair suitable for redundant backbone links between data centers?
Absolutely; the matched pair provides high-capacity, long-distance backbone links with DDM monitoring—exactly what data centers need for reliable inter-facility connectivity.
How quickly can Procure.ae ship matched transceiver pairs?
Procure.ae stocks MikroTik fiber optics across the UAE and GCC on a request-a-quote basis. Contact the team to confirm availability of matched pairs and delivery timelines.
Does Procure.ae assist with dual-fiber backbone design and deployment?
Procure.ae provides transceiver guidance and compatibility consultation. For network design, fiber route planning, and professional installation, contact the team to discuss comprehensive deployment services.
What is supplied in the S-3553LC20D package?
The package includes a matched pair: the S-35LC20D (1310nm) and S-53LC20D (1550nm), each with LC connectors, protective caps, and documentation. Contact Procure.ae to confirm if test certificates or warranty information are included.
Why are complementary wavelengths important in this pair?
The 1310nm and 1550nm wavelengths have minimal crosstalk, allowing clean bidirectional transmission over one fiber. Contact Procure.ae for wavelength specifications and WDM filter requirements.
Is there warranty coverage for matched fiber transceiver pairs?
MikroTik includes limited hardware warranty for manufacturing defects. Contact Procure.ae for specific warranty terms, pair replacement procedures, and any extended protection available.
