Copper RJ-45 transceiver module BlueOptics RDH90156/1-R2A-BO SFP 100m

The BlueOptics RDH90156/1-R2A-BO Copper RJ-45 transceiver module is an SFP form-factor 10/100/1000BASE-T network transceiver with a single RJ-45 Ethernet port. Designed for short-range copper connections, it supports data transmission up to 100 m over standard twisted-pair cabling and weighs approximately 20 g. The module follows MSA-compliant SFP mechanical and electrical specifications and is intended for use in compatible network equipment that accepts SFP copper modules.

Advantages

The module provides a compact SFP-based RJ-45 interface that enables flexible deployment in switches, routers and other SFP-capable devices without occupying a larger form factor. Its support for 10/100/1000 Mbps operation ensures backward compatibility with existing Fast Ethernet and Gigabit Ethernet links. The lightweight design and standardized SFP connectivity simplify installation and interchangeability across supported hardware platforms.

Key specifications

How to use

Insert the BlueOptics RDH90156/1-R2A-BO SFP module into an empty SFP slot on supported network hardware while the device is powered down or following the manufacturer's hot‑swap guidance. Connect a suitable RJ-45 patch cable from the module to the copper network endpoint. Ensure link speed and duplex settings are configured or left to auto‑negotiate per your network policy. Verify link status on the host device and test connectivity across the intended cable run up to 100 meters.

Recommendations

Use the module with quality Cat5e or Cat6 cables for runs up to 100 m and confirm that the host device supports SFP copper modules and any required diagnostic features. For critical links, verify compatibility with the specific switch or router firmware and enable auto-negotiation to avoid mismatched speed or duplex settings.
