HS-2G8E

Q: Why choose the HS-2G8E over a single-uplink switch?

The second 1.25G fiber port is the point: it lets you daisy-chain uplinks and build surveillance rings where nodes pass traffic to the next cabinet while eight gigabit RJ45 ports serve local cameras or access switches. It is the standard building block for ring and chain topologies, on the Realtek chipset with a 20 Gbps backplane.

Q: Which fiber versions should I order?

For 20 km: S20 dual-fiber, or the A20/B20 single-fiber WDM pair (TX 1310 / TX 1550 nm) — remember that A and B units must face each other on the same strand. Longer links use the 40 km dual-fiber or BiDi options. All versions support 850/1310/1490/1550 nm optics and cover 550 m multi-mode up to 100 km single-mode.

Q: Is it suitable for outdoor cabinets?

Yes — lightning and surge protection is built in for pole and street cabinets. The 215 × 107 × 26 mm metal case is wall-mountable and fanless, consumes 2.2–4.5 W from an AC 100–240 V or DC 5 V supply, and provides a 4K MAC table with 9216-byte jumbo frames. Warranty is 1 year.

Product Overview

The HS-2G8E extends your LAN over fiber with 2 × SC fiber ports + 8 × RJ45 — a gigabit solution for point-to-point fiber links between switches, routers and remote equipment. Store-and-forward switching, auto-negotiation and MDI/MDI-X keep installation plug-and-play; the metal housing mounts on walls or in cabinets. Multimode 550 m to single-mode 120 km optics available — send the distance and port count for an exact quote.
