Product Description
1.25Gbps Ethernet Over Fibre Extender
The BLAEOF11 Ethernet Over Fibre Extender is an advanced fibre media converter designed to bridge the gap between copper-based network signals and fibre optic systems. Ideal for network expansions, it provides seamless translation of short-range electrical signals to long-range optical signals over a fibre optic connection.
Key Features:
- Compact and Versatile Design: Equipped with a Small Form-factor Pluggable (SFP) interface and LC optical connector, offering easy installation and compatibility with standard network configurations.
- High-Speed Data Transmission: Supports up to 1.25Gbps data rate, making it suitable for applications requiring fast and reliable data transfer.
- Extended Reach: Capable of reaching distances of up to 10 kilometres over fibre, ensuring network coverage across large areas.
- Low Power Consumption: Efficient design with less than 5W power consumption.
- Robust Compatibility: Supports 1000Base-BX Ethernet and MSA compliance, with built-in diagnostics for ease of monitoring and maintenance.
- Hot-Pluggable and Dual Mode Support: Enables seamless switching and supports multi-mode and single-mode fibre, allowing for flexibility in setup.

I called today and spoke with Daren regarding TV signal advice. He was very knowledgeable and extremely helpful. Thanks so much Daren for the brilliant customer service provided. 👍🏻👍🏻

I was pleased with the price and items received however the experience was somewhat marred by DX Couriers. Expecting 2 items in the shipment they only delivered 1 and tracking confirmed 1 of 2 scanned onto delivery vehicle. When I contacted DX they confirmed the second parcel was still in Sheffield at the collection depot. This meant I had to wait in a second day for the rest of the order to arrive.
