MikroTik HS-85DLC05D SFP optical module MM 550m 1 25G 850Nm

MikroTik HS-85DLC05D — SFP Optical Module for Multi-Purpose Networks

For users looking for a powerful and flexible multimode optical fiber module, the MikroTik HS-85DLC05D is the ideal solution. This module supports 1G and 2.5G data rates, allowing network upgrades without replacing existing infrastructure. With a range of up to 550 m and operating at a wavelength of 850 nm, it is suitable for corporate networks, industrial environments, and ISP infrastructure. With a LC duplex connector and built-in digital diagnostics DDM, it ensures easy integration and efficient management.

Performance and throughput

The MikroTik HS-85DLC05D enables data transmission at 1G or 2.5G speeds, providing flexibility in network scaling. The transmitter optical output power in the range of -9 to -3 dBm and the receiver sensitivity (OMA) up to -18 dBm guarantee reliable transmission even in more difficult conditions. Thanks to multimode transmission at the wavelength of 850 nm, the module can be easily integrated into existing networks without the need for significant modifications.

Digital diagnostics and monitoring

The built-in digital diagnostics DDM allows continuous monitoring of key parameters such as optical power, voltage, temperature and laser diode current. This feature allows users to set their own thresholds for warning when limits are exceeded, which simplifies proactive network management. The ability to detect abnormal conditions early contributes to higher reliability and maintenance efficiency.

Loss of Signal (LOS) signaling

The module is equipped with a loss of signal (LOS) signaling function that provides an open collector output. In normal operation, it is a logic 0, while in the event of signal loss, it switches to a logic 1. The LOS output requires a 4.7 kΩ-10 kΩ pull-up resistor on the host device side. The 0.5 to 5 dB LOS hysteresis ensures reliable detection.
