SFP copper transceiver BlueOptics BO08C28S1 1000 Mbit/s Gigabit Ethernet, RJ45

The BlueOptics BO08C28S1 SFP copper transceiver provides a compact, hot‑swappable Gigabit Ethernet interface in an SFP form factor with an RJ45 connector. It converts an SFP slot into a 1000 Mbit/s copper Ethernet port, allowing switches, routers and media converters to support short‑range copper uplinks without occupying a full-size module bay. The module is intended for use in confined installations such as telecom cabinets, office network racks and small data center patch panels where space efficiency and straightforward copper connectivity are required.

Advantages

This SFP copper transceiver delivers standard Gigabit Ethernet performance over copper cabling while maintaining compatibility with equipment that accepts SFP modules. The RJ45 interface supports standard CAT5e/CAT6 links for short‑distance connections and the hot‑swappable SFP format enables maintenance or upgrades without powering down the host device. The small form factor reduces port footprint compared with integrated RJ45 ports and provides flexibility when configuring uplinks or adding spare ports.

Suitable for

• Converting SFP slots to 1000BASE‑T copper uplinks
• Connecting switches, routers and media converters within racks and telecom closets
• Short‑reach links in offices, wiring closets and compact data center environments
• Hot‑swap upgrades and spare port provisioning without network downtime

Key specifications

• Data rate: 1000 Mbit/s (Gigabit Ethernet)
• Form factor: SFP (Small Form‑factor Pluggable)
• Connector: RJ45 (8P8C) for copper twisted pair
• Supported cabling: Unshielded or shielded twisted pair (e.g., CAT5e, CAT6) for typical short‑reach links
• Range: Designed for short‑distance copper connections (typical up to 100 m over appropriate cabling)
• Hot‑swappable: Yes
• Operating environment: Standard commercial temperature ranges for networking equipment

How to use

Insert the SFP copper transceiver into an available SFP slot on a compatible switch, router or media converter, ensuring proper orientation until it latches. Connect an RJ45 patch cable between the transceiver and the remote network device or wall outlet. The host device will negotiate link speed and duplex according to standard Gigabit Ethernet auto‑negotiation. For removal, unlatch the module and extract it while the host supports hot‑swap; follow the host vendor’s procedures if the device requires any specific actions before module removal.

Recommendations

Use quality CAT5e or CAT6 cabling and properly terminated RJ45 connectors for reliable Gigabit performance. Verify that the host device supports SFP copper modules and check firmware compatibility if required. For runs approaching the upper distance limit, test the link to confirm stable performance and consider upgrading cabling if errors or reduced throughput are observed.
