Ubiquiti EdgeRouter X SFP Gigabit Router (ER-X-SFP)

Ubiquiti EdgeRouter X SFP Gigabit Router (ER-X-SFP) is a small form-factor pluggable module, for Ubiquiti routing equipment.

One thing that catches people out on optics more than anything else: vendor coding. Ubiquiti equipment generally expects Ubiquiti-coded modules, and a module without the right coding may be refused outright or raise a persistent alarm even when it is electrically identical to the correct part. Some platforms allow an unsupported-transceiver override and some do not, and where it exists it can affect your support position. We supply coded modules for that reason.

This listing carries no specification text, which is why this page describes the family rather than the exact configuration. Routers of the same model were frequently sold in several configurations differing in memory, interface cards, power supply and licensing, and those differences matter more than the model name does. We can pull the exact specification for this part number from the vendor’s own database before you order.

Three questions worth answering before any router purchase, whatever the model. What the throughput requirement actually is with your feature set enabled, rather than the datasheet figure measured without it. Whether the features you need are licensed as well as present, since on most platforms security and performance are separate entitlements. And how many slots or ports you will need in three years, because adding capacity is cheap and replacing a chassis is not.

Send us the port at each end, the fibre you have and the distance, and we will confirm this is the right module or point you at the one that is.

Green Code Technologies is a supplier of Ubiquiti, and we supply Cisco, Huawei and Juniper networking alongside HPE, Dell, Samsung, Netgear and Asus. We would rather tell you a part is no longer supported, or that we need to check it, than take an order for something that will not do what you need.

The Ubiquiti EdgeRouter X SFP (SKU: ER-X-SFP) is a compact and cost-effective Gigabit router designed for SMB, home, and WISP deployments. It combines advanced routing features with flexible connectivity, including fiber uplink support.

This router features 5× Gigabit Ethernet RJ45 ports and 1× Gigabit SFP port. As a result, it supports both copper and fiber connectivity for WAN and LAN configurations. It also includes an integrated switch chip with hardware offloading. Therefore, it improves performance for local traffic and routing tasks.

The ER-X-SFP supports 24V passive PoE input on one port and configurable PoE passthrough on another port. As a result, it can be powered by a PoE source and supply power to compatible Ubiquiti devices such as airMAX radios.

The device runs EdgeOS, which supports advanced Layer 3 routing protocols such as static routing, OSPF, and BGP. In addition, it includes features such as VLANs, QoS, firewall policies, NAT, and VPN services. Therefore, it provides secure and flexible network management.

For performance, the router supports hardware-accelerated packet processing. It ensures stable throughput for typical SMB and edge networking use cases.

The ER-X-SFP features a compact desktop form factor with fanless operation. Therefore, it is suitable for quiet environments such as offices and home networks.

This router is ideal for small businesses, branch offices, and WISP edge deployments requiring fiber connectivity and PoE flexibility in a compact design.
