The IEEE 802.3z standard includes 1000BASE-SX for transmission over multi-mode fiber, 1000BASE-LX for transmission over single-mode fiber, 100BASE-FX is a version of Fast Ethernet over optical fiber. It uses a 1300 nm near-infrared (NIR) light wavelength transmitted via two strands of optical fiber, one for receive(RX) and the other for transmit(TX), 100BASE-SX is a version of Fast Ethernet over optical fiber. It uses two strands of multi-mode optical fiber for receive and transmit. ASCS offers the whole series of FE and GE optical fiber transceivers. Including: SFP-SX MM 550M SFP-LX SM 10-20KM SFP-EX SM 40KM SFP-ZX SM 80KM SFP-EZX SM 120KM SFP-CWDM SFP-DWDM SFP-BIDI

QSFP+ (Quad Small Form-factor Pluggable Plus) Cables Assemblies QSFP+ copper direct-attach cables are suitable for very short distances and offer a highly cost-effective way to establish a 40-Gigabit link between QSFP+ ports of QSFP+ switches within racks and across adjacent racks. These cables are used for 40GbE and Infniband standards to maximize performance.If you need customized services, please contact info@ascsusa.com for more details.

ASCS’s QSFP-40G-SR4 Module supports link lengths of 100m and 150m respectively on laser-optimized OM3 and OM4 multimode fiber cables. It primarily enables high-bandwidth 40G optical links over ribbon fiber cables terminated with multi-fiber connectors, and could also be used along with ribbon to duplex fiber breakout cables for connectivity to four 10GBASE-SR optical interfaces. This QSFP-40G-SR4 is built according to Cisco specifications, and is 100% compatible with Cisco System. If you need customized services, please contact info@ascsusa.com for more details.
