- Description
- The ETL’s RF Over Fibre transmit (TX) modules convert radio frequency (RF) signals into optical signals for transmission over fibre optic cables. The process involves modulating an RF signal onto a light wave using a laser, transmitting it through fibre optic cables. At the receiving end, the optical signals are converted back into RF signals using RF Over Fibre receiver (RX) modules. The RF over Fibre systems are used as an alternative to traditional copper coaxial cable. Fibre optics have lower signal attenuation compared to copper cable, ensuring better signal quality over long distances. ETL’s RF Over Fibre modules ensure signal integrity through high-quality components and advanced design techniques. The use of low-noise lasers and photodetectors minimises signal distortion and noise. Additionally, the modules are designed to maintain linearity and minimise signal degradation, ensuring that the transmitted signal retains its quality and accuracy over long distances. This is particularly beneficial in satellite ground stations, where long-distance transmission is common, and the size and weight of copper cables can be limiting factors. ETL’s RF Over Fibre modules are designed to support a wide frequency range used in satellite communications, including L-band, S-band, C-band, and Ku-band. The ETL’s RF Over Fibre modules are designed to be housed within an indoor or outdoor chassis for environmental protection.

- Justification
- Classification has been determined in accordance with the following: For the purposes of determining the commodity codes within which goods most appropriately fall, Reg 3 (1) of The Customs Tariff (Establishment) (EU Exit) Regulations 2020 sets out that the rules of interpretation contained in the following have effect – a. Part Two (Goods Classification Table Rules of Interpretation) of the Tariff of the United Kingdom (Reg 3(1)(a); and b. Notes to a section or chapter of the Goods Classification Table (Reg 3(1)(b) General Interpretative Rules (GIRs): GIR 1 has been used to classify this product by the terms of heading 8517 - Telephone sets, including smartphones and other telephones for cellular networks or for other wireless networks; other apparatus for the transmission or reception of voice, images or other data, including apparatus for communication in a wired or wireless network (such as a local or wide area network), other than transmission or reception apparatus of heading 8443, 8525, 8527 or 8528 GIR 6 has been used to classify the goods to sub-heading – 851762 - Machines for the reception, conversion and transmission or regeneration of voice, images or other data, including switching and routing apparatus Also classified in accordance with: Harmonised Standard Explanatory Notes (HSENs) to heading 8517
