December 11, 2008 -- Fostec Inc., a fiber optic manufacturer based Seoul, South Korea, has introduced a series of optical communication devices for FTTH network systems. The devices, aimed at the global market, include media converters, fiber distribution accessories, PLC splitters, fiber optic connectors, and variable optical attenuators. Applications include FTTX, CATV, LANs, telecommunications networks, and optical divergence for network transmission and distribution.
The Fostec copper-to-fiber media converter delivers half or full-duplex Ethernet transmissions of 10/100 Mbps. Features include link loss forward (LLCF) and link loss return (LLR), MDI to MDIX auto negotiation (A/N), easy system configuration by DIP, A/N or manual 10/100M and HDX/FDX selection, fiber optic segment extension up to 2 km multimode and 120 km singlemode, status monitoring via front LED display, STP/UTP cabling support, and far-end-fault detection. The converter also supports IEEE 802.3u 100BaseTx, the CSMA/CD standard, and half/full duplex mode.
Fostec's quick termination connector, dubbed e-SC [expedient subscriber connector], is billed as an easy-to-build optical fiber connector, using simple tools such as mini-drivers, that does not require any polishing or specific tools for the optical fiber. The SM cable used by the e-SC has diameters of 3.0 mm, 2.0 mm, 0.9 mm and meets the ANSI/TIA/EIA-568-A standard. The cable assembly is designed to deliverd superior performance under the wavelengths of 1310- and 1550-nm, with an average insertion loss of less than 0.5 dB and return loss of more than 45 dB.
Fostec has also developed planar lightwave circuit splitters and variable optical attenuators that can be applied to FTTX systems, as well as LAN/WAN, Metro networks, analog/digital passive networks, CATV networks, and other optical fiber telecommunication systems. The PLC splitters come with 1:4, 1:8, 1:16, and 1:32 ports. The company has also developed and optical fiber distribution (OFD) products in sizes such as mini optical fiber distribution (M-OFD), which is made with ABS-PVC materials for simpler installation in terminal boxes and small size optical fiber distributions of 1 to 8 cores.
Soo Young Lee, CEO of FOSTEC, comments, "We are experienced expert in FTTH optical communications technology, and our newest products such as optical connector, optical patch cord, hybrid optical cable, optical communication adaptor, and optical network extenders will be able to serve the need of our customers with excellent performance and quality."
