1.Modal bandwidth applies only to multimode fiber.
2.A mode-field diameter/cladding diameter = 9 micrometers/125 micrometers.
3.A mode-conditioning patch cord is required. Using an ordinary patch cord with MMF or 1000BASE-LX/LH SFP modules and a short link distance can cause transceiver saturation and an elevated bit error rate (BER). When using the LX/LH SFP module with 62.5-micron diameter MMF, you must also install a mode-conditioning patch cord between the SFP module and the MMF cable on both the sending and receiving ends of the link. The mode-conditioning patch cord is required for link distances greater than 984 feet (300 m).
4.1000BASE-ZX SFP modules can send data up to 62 miles (100 km) by using dispersion-shifted SMF or low-attenuation SMF; the distance depends on the fiber quality, the number of splices, and the connectors.
Installing the Chassis
The controller ships with rack mounting brackets and the desktop or shelf mounting rubber feet in a separate bag.
An adjustable rack-mount kit is included for mounting the controller in a standard 19-inch (48.3 cm) equipment rack. A standard equipment rack has two unobstructed outer posts, a minimum depth between the front and rear mounting posts of 13 inches (33 cm), and a maximum depth of 32 inches (81.3 cm).
You can also install the controller in a 2-post equipment rack.
This kit is not suitable for racks with obstructions (such as a power strip) that could impair access to system components.
