February 9, 2005 Somerset, NJ -- Emcore, a provider of compound semiconductor-based components and subsystems, today announced the release of its 10-Gigabit Ethernet (10-GbE)compatible XENPAK module # EEX-8100-XEN (EX4), which enables extended distance transmission over both multimode and single-mode fibers.
The proprietary EX4 module plugs into the company's standard XENPAK slots and can transmit up to 1 km across legacy multimode fiber, and up 1.5 km on some higher grade legacy multimode fibers. The module can also transmit up to 40 km over single-mode fiber. The EX4 enables multimode links of embedded stranded fibers longer than 300 m to upgrade to 10-GbE.
Dr. John Dallesasse, Director of Development for Emcore's Fiber Optics Division, explains, "Having a single port type that is capable of reaching all of the distance objectives originally targeted by the IEEE 10 Gigabit Ethernet standard is very important. The EX4 module supports 40 km operation yet does not saturate with short fiber lengths, allowing end-users to 'plug-and-play.' The EX4 should vastly improve the upgrade path for customers maintaining multimode fiber infrastructures in their workgroup and enterprise networks."
The company's EX4, CX4, and LX4 modules combine to support 10-GbE across all WANs and MANs, at distances ranging from 1m to 40km.
