The S800 Optical FireWire Repeaters (M4-200 and M4-201) offer 500m (1,640feet) extension over the limits of copper wire extension, 4.5m (15feet) without any distribution amplifiers or repeaters. The basic model, M4-200 consists of a pair of two repeaters, having one-optical and two-electrical ports. Additionally, between two, multiple installation of M4-201, having two-optical and one-electrical ports provides a long fiber-optic extension of additional 1394 devices. The M4-201, giving connection of a 1394 device is capable of two-way fiber connection in forward and backward directions, which eventually makes a daisy chain with each repeater of M4-200 at both ends.
Duplex multi-mode glass of fiber (MM GOF) cables with LC connectors makes fiber connection between repeaters.
The electrical bilingual port of 1394b-2002 standard supports S800 (800Mbps) data rate, fully complied with IEEE1394b-2002, but also backwardly S400, S200, and S100 by using DS (9 pin or 4 pin)-to- bilingual cables.
When applying to IEEE1394 devices or controllers having powers themselves, the M4-200 repeater requires plugging the external DC power adapter in shipping package, only when the power indicating LED is off.
