Kupari-lähetin-vastaanotinmoduuli BlueOptics B248-BO 1250 Mbit/s RJ-45

The BlueOptics B248-BO is a copper SFP transceiver module designed for network equipment that accepts SFP form-factor modules. It provides a single 10/100/1000-compatible copper port using an RJ-45 connector and supports a maximum data transfer rate of 1250 Mbit/s. The module operates at an input voltage of 3.3 V and is housed in a metal casing finished in silver, with a lightweight construction of approximately 20 g, suitable for deployment in switches, routers and media converters that require a compact, hot-pluggable copper interface.

Advantages

The module's compact SFP form factor allows for space-efficient port density in rack-mount and modular network devices. The RJ-45 copper interface enables direct connection to standard Ethernet cables without additional media converters. Metal housing offers mechanical durability and electromagnetic shielding while the low weight supports straightforward handling and installation. Operation at 3.3 V makes it compatible with standard SFP power supplies.

Key specifications

How to use

Insert the BlueOptics B248-BO into an available SFP slot on a compatible network device with the module's orientation aligned to the slot guide. Ensure the host device is powered and supports copper SFP transceivers at the required speed. Connect a standard RJ-45 Ethernet cable to the module's port and to the remote device. The module supports hot-plug operation; allow the host device to recognize and configure the link. Verify link status and negotiated speed in the host device's management interface.

Recommendations

Use Cat5e or better twisted-pair cabling for reliable operation at the supported data rate. Avoid exposing the module to excessive mechanical stress or moisture; install in equipment with proper ventilation and ESD protection. When replacing or installing modules, follow the network device manufacturer's guidance for supported transceiver types and firmware compatibility to ensure link stability.
