It is very similar to 1000BASE-LX10 but achieves longer distances up to 40 km over a pair of single-mode fibers due to higher quality optics than a LX10, running on 1310 nm wavelength lasers. It is sometimes referred to as LH (Long Haul), and is easily confused with 1000BASE-LX10 or 1000BASE-ZX because the use of -LX(10), -LH, -EX, and -ZX is ...
Generally, layers are named by their specifications: [8] 10, 100, 1000, 10G, ... – the nominal, usable speed at the top of the physical layer (no suffix = megabit/s, G = gigabit/s), excluding line codes but including other physical layer overhead (preamble, SFD, IPG); some WAN PHYs (W) run at slightly reduced bitrates for compatibility reasons; encoded PHY sublayers usually run at higher ...
10BASE-F, or sometimes 10BASE-FX, is a generic term for the family of 10 Mbit/s Ethernet standards using fiber-optic cable.In 10BASE-F, the 10 represents a maximum throughput of 10 Mbit/s, BASE indicates its use of baseband transmission, and F indicates that it relies on a medium of fiber-optic cable.
Ethernet over twisted-pair technologies use twisted-pair cables for the physical layer of an Ethernet computer network. They are a subset of all Ethernet physical layers.. Early Ethernet used various grades of coaxial cable, but in 1984, StarLAN showed the potential of simple unshielded twisted pair.
100BASE-ZX is a non-standard but multi-vendor [29] [better source needed] term to refer to Fast Ethernet transmission using 1,550 nm wavelength to achieve distances of at least 70 km over single-mode fiber. Some vendors specify distances up to 160 km over single-mode fiber, sometimes called 100BASE-EZX.
LX – 1310 nm, for distances up to 10 km (originally, LX just covered 5 km and LX10 for 10 km followed later) EX – 1310 nm, for distances up to 40 km ZX – 1550 nm, for distances up to 80 km (depending on fiber path loss), with green extraction lever (see GLC-ZX-SM1)

The T/S 1500 was an upgraded T/S 1000 with a better keyboard and 16 KB RAM, introduced in 1983. [8] [9] Timex Sinclair (TMX Portugal) designed the T/S 1500 and offered it to the Timex Corporation. The design utilized the T/S 2000 prototype (ZX Spectrum-like) silver cases that weren't previously used because of the launch of the T/S 2068.
