Two main types of optical fiber used in optical communications include multi-mode optical fibers and single-mode optical fibers. A multi-mode optical fiber has a larger core (≥ 50 micrometers), allowing less precise, cheaper transmitters and receivers to connect to it as well as cheaper connectors. First developed in the 1970s, fiber-optics have revolutionized the industry and have played a major role in the advent of the.

The FP-5 "Flamingo" is a Ukrainian ground-launched cruise missile developed by defence firm Fire Point. Revealed on 18 August 2025, the missile is fitted with a 1,150 kg (2,540 lb) warhead and has a range of 3,000 km (1,900 miles). The missile, similar in appearance to the Milanion Group FP-5 cruise missile, is in serial production, targeting 210 units a month.

This gives it a superficial resemblance to the and the Ukrainian-built Soviet and reconnaiss. The Czech crowdfunding initiative "Gift for Putin" ("Dárek pro Putina") raised approximately $520,000 (roughly 12.

Key differences between switch optical ports and Ethernet ports: ▶ Different Transmission Rates: Optical ports commonly support speeds exceeding 100G, while Ethernet ports typically max out at 10G. Ethernet switch port types define the performance, scalability, and architecture of modern networks. RJ45 ports serve access-layer copper connections; SFP/SFP+ ports enable flexible 1G/10G uplinks; SFP28 delivers 25G for modern data centers; QSFP+ and QSFP28 support high-density 40G/100G spine–leaf. The SFP port is commonly found on Gigabit Ethernet switches and is primarily used for fiber optic device connections or for uplinking 1G switches to aggregation/core layer devices, providing higher-bandwidth links. SFP replaces the formerly common gigabit interfac converter (GBIC), and SFP is also called Mini-GBIC.
