Network Expansion Module

Key Features

• 1x3 to 2x16 as standard

• Fused fiber and planar technology

• Low excess loss and PDL

• Single and dual window operation

• High and standard grades

• Custom configurations available

Applications

The JDSU network expansion module enables the splitting of optical signals in

singlemode optical fiber. The standard product comprises one or two input ports

and between three and 16 output ports. Designed for optical networking

applications, the module uses advanced fused fiber and planar technology to yield

ultra-low excess loss and low polarization dependent loss (PDL) in a compact package.

• Passive optical networks

• Secure data networks

• CATV

• Scientific equipment

Standard wavelength ranges are 1310, 1550, 1585 nm and 1310/1550 nm. A wide

variety of housings, including an injection-moulded fiber organizer, 19” rack, and

LGX cassette are available and most connector types can be fitted.

Two grades of performance are provided: Grade P modules offer the solution to

demanding power and PDL budgets through the use of the highest specification

couplers. Grade A modules offer a cost-effective answer to standard splitter

requirements, including CATV and access networks.

In addition to the standard products shown, a wide variety of custom

configurations are available for specialized applications. These include alternative

housings, wavelengths, and high port counts over 16.
