NET TRANSCEIVER SFP/HS-85DLC05D MIKROTIK

Network engineers deploying Gigabit Ethernet over multimode fiber in enterprise LANs or data centers can rely on the MikroTik HS-85DLC05D SFP transceiver. This hot-pluggable module delivers 1.25 Gbps over 850 nm VCSEL, reaching up to 550 meters on OM2/OM3/OM4 multimode fiber with an LC duplex connector. Digital diagnostics monitoring (DDM) provides real-time visibility into temperature, voltage, laser bias, and optical power, simplifying troubleshooting and proactive maintenance.

Why choose it

The HS-85DLC05D is engineered for reliable, high-performance short-reach fiber connectivity. Its industrial temperature rating ensures operation in harsh environments, from unheated cabinets to outdoor enclosures. With DDM, you gain actionable insights to prevent downtime and optimize link performance. Fully compatible with MikroTik routers and switches, it also works in any MSA-compliant SFP port, offering flexibility across mixed-vendor networks.

Ideal use cases

• Gigabit Ethernet uplinks between switches in campus or building backbones
• Server-to-switch connections in data centers using multimode fiber
• Industrial networks requiring wide temperature tolerance
• Upgrading existing multimode fiber infrastructure to 1G without replacing cabling

Good to know

This transceiver supports duplex LC connections and is intended for multimode fiber only. For longer distances or single-mode fiber, consider a different model. The module is backed by MikroTik's reputation for quality and value, making it a cost-effective choice for both new deployments and spares inventory.
