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.

Very prompt reply re order unfortunately delivery by DPD failed to deliver to address even though there was a person in. DPD delivered to a local drop off point for collection, the so called local post office which not that local!!! Otherwise there would be 5 stars!!! Product great and fitted to cover entry point of Sky cables into building as SKy's product has failed , plastic cracked and fallen off.

I bought a LNB adapter for a Sky dish to allow me to use a single outlet LNB. Fitted perfectly.

I understand from my inquiry that your stock was low and is why the order was later than anticipated. It have been appreciated if it had communicated to me without me contacting you first, as I had had no information since the initial order confirmation. Having said that once the item was available it was dispatched and arrived within 24 hours and appears to be a quality product, although I have not installed it yet.

Good product and a fair price. A pleasure to deal with friendly company. After researching other products, and other companies, I settled for a suitable serial from Blakes. I have a history of studying aerials and worked in the TV trade some time ago, and the quality of their products impressed me.
