MikroTik S+31DLC10D 10G SFP+ LR 1310nm 10km LC

The MikroTik S+31DLC10D is a reliable, cost-efficient 10G SFP+ module engineered for backbone links, campus networks, industrial deployments, and ISP infrastructure where long-reach single-mode fiber is required.

Running at 1310 nm over dual-LC connectors, it supports full-duplex operation across links up to 10 km on standard single-mode fiber — the same reach as the XS+31LC10D, but at nearly half the price. If your deployment is 10G-only and you do not need 25G SFP28 compatibility, the S+31DLC10D is the smart choice.

Built-in Digital Diagnostics Monitoring (DDM) provides continuous visibility into key optical parameters — enabling proactive maintenance and data-driven upgrade planning without adding external test equipment.

Key features:

- 10G SFP+ single-mode — full-duplex, up to 10 km reach

- 1310 nm wavelength — widely supported across switches, routers, and media converters

- Dual-LC connector for standard single-mode fiber patch cables

- Built-in DDM — real-time monitoring of optical power, voltage, temperature, and laser bias current

- Industrial-grade reliability — MTBF ~100,000 hours at 25°C

- Direct alternative to XS+31LC10D at approximately half the price

- Product code: S+31DLC10D

Compatible with: MikroTik switches and routers with SFP+ ports, as well as third-party equipment from Cisco, Ubiquiti, Juniper, and other vendors supporting standard 10G SFP+ LR modules.

Ideal for: ISP backbone uplinks, enterprise campus fiber rings, industrial network backbones, data centre inter-switch links, and any 10G deployment where long-reach single-mode fiber is in use.
