Product Information

Overview

The MikroTik S-3553LC20D is a matched pair of 1.25G single-mode bidirectional (BiDi) SFP transceivers designed for fiber connections up to 20 km. The kit includes one S-35LC20D and one S-53LC20D module, using complementary transmit and receive wavelengths to provide bidirectional communication over a single fiber strand.

The S-35LC20D transmits at 1310 nm and receives at 1550 nm, while the S-53LC20D transmits at 1550 nm and receives at 1310 nm. Both modules feature a single LC connector and support Digital Diagnostic Monitoring (DDM) for monitoring optical transceiver performance.

Designed for MikroTik devices equipped with compatible SFP ports, the S-3553LC20D provides a practical solution for extending Gigabit fiber connections between network locations while using a single fiber strand.

Ideal Applications

  • Long-Distance Gigabit Fiber Connections
  • Single-Fiber Bidirectional Network Links
  • ISP & Network Infrastructure Deployments
  • Fiber Connections Between Remote Network Sites
  • Single-Mode Fiber Network Expansion

Highlights

Key Features

Complete Bidirectional SFP Pair

Includes two complementary 1.25G SFP transceivers, the S-35LC20D and S-53LC20D, designed to establish a bidirectional fiber connection using a single fiber strand.

Up to 20 km Single-Mode Fiber Reach

Supports single-mode fiber connections up to 20 km, making the kit suitable for connecting distant network locations and extending Gigabit network infrastructure.

Complementary 1310/1550 nm Wavelengths

The S-35LC20D transmits at 1310 nm and receives at 1550 nm, while the S-53LC20D transmits at 1550 nm and receives at 1310 nm, enabling two-way communication over a single fiber.

Digital Diagnostic Monitoring (DDM)

Both transceivers support Digital Diagnostic Monitoring, providing diagnostic information for monitoring optical module operation and supporting network troubleshooting.
