Tyco Electronics has an AMP Netconnect Gigabit Ethernet mode-conditioning cable assembly that has been approved by Cisco and given one of its part numbers The new mode-conditioning assembly is designed for use in 62.5/125 multimode fibre-optic cabling systems, where these assemblies allow long-wavelength (1300nm) signals to be transmitted over good-quality fibre at distances of up to 550m

System protects critical data in harsh environment
The AMP Netconnect EtherSeal connectivity system is designed to protect critical data communication in harsh environments.
The LX long-wavelength devices used in Gigabit Ethernet applications are based on a single-mode launch condition, and operate over both single-mode and multimode fibre.
Differential mode delay occurs when the transmitter device launches a single-mode laser signal into the centre of a multimode fibre, resulting in the transmission of multiple signals.
Such signals can confuse the receiver device, with resultant limitations on the operating bandwidth of Gigabit Ethernet.
The 62.5/125 fibre will typically only allow a distance of 220-270m for Gigabit Ethernet using lower-cost lasers operating at the 850nm (SX wavelength), and longer distance requirements have to be met by the use of 1300nm electronics in conjunction with a mode-conditioning launch lead.
The AMP Netconnect mode-conditioning cable assembly eliminates differential-mode delay by moving the single-mode launch to an offset position away from the centre of the fibre where most impurities are found.
The lead carries AMP Netconnect Part number 1536259-3 and Cisco Part Number 72-1517-01.
