Inside Plant: FxDS Optical Component Chassis (OCC)
Optical component chassis from Clearfield offer you the flexibility and performance you need to meet today’s most demanding applications. Designed for industry standard packaging as well as Clearfield designed packaging.
Chassis Options – Clearview Cassette with FieldSmart Optical Component Chassis
The Clearview Cassette houses the optical component to directly integrate with the FieldSmart Fiber Scalability Center (FSC) for outside plant environments, and with the FieldSmart Fiber Crossover Distribution System (FxDS) for central office applications. Its modular fiber cable management lets you scale your network for maximum network density, scalability and flexibility.
Horizontal Modular Optical Component Chassis
On-frame chassis for inside plant applications that is designed to house optical components such as splitters and WDMs. This Clearfield designed chassis is available in 1 RU, 2 RU, 6 inch and 11 inch heights and can mount into a 19” or 23” frame. With industry leading density, this density incorporates FieldSmart’s horizontal 1, 2, 3 and 6 high packaging.
Vertical (LGX-Style) Modular Optical Component Chassis
On-frame chassis for inside plant that is designed to house optical components such as splitters and WDMs. This chassis is 6 inches high and will accommodate industry standard 1, 2, 3 and 4 wide modules.
Optical Component Packaging Options
FxDS Modular Optical Components (MOC)
Modular optical components are needed when an optical splitter or WDM is required in an inside plant environment. Modular optical components are splitters or WDM’s that are packaged inside a metal or plastic housing with female adapters on the front and then inserted into the optical component chassis. The FieldSmart and LGX modules require an optical component chassis to house the modules in a frame.
The one rack unit splitter does not require a separate chassis and is available in 19” or 23” mounting versions.
FieldSmart Modular Optical Components (MOC)
Available in 1, 2, 3 and 6 high units, these Clearview Multiplied components are designed to be installed into the FieldSmart optical component chassis and provide the highest density solution in the industry.
LGX Modular Optical Components (MOC)
Available in 1, 2, and 4 wide units. These industry standard LGX style units can be installed into a LGX optical component.
1 x 32 Frame Mounted Splitter
This Clearfield designed 1 × 32 splitter is offered in a 1 RU (1.75”) footprint. Integrates directly with Clearfield’s 19” and 23” frame systems.
Other Component Options
Wavelength Division Multiplexers (WDMs)
Wavelength division multiplexers let you expand the bandwidth of optical communication networks. They can be used at several locations within each network. Clearfield provides WDMs for both singlemode fiber and multimode fiber applications.
A wavelength division multiplexer is used in an FTTH network to combine 1490/1550 wavelengths from the OLT/VLT onto a singlemode fiber for transmission through the communication network, using the 1310 signal for return path. At the receiver end, a WDM is used to separate the wavelengths for reading the information transmitted on each channel.
These devices can be used for coarse wavelength division multiplexing (CWDM, 20 nm channel spacing), dense wavelength division multiplexing (DWDM, 100 GHz and 200 GHz channel spacing), and broad wavelength band division (e.g., 1310 nm and 1550 nm). DWDM channels are tuned to the ITU wavelength grid. Clearfield offers standard 4, 8, and 16 channel counts, plus custom fabricated wavelength division multiplexers for any channel count between 2 and 16.
Splitters
An optical splitter allows for the transmission of video, audio and data signals from one fiber optic transmitter to multiple receiver units simultaneously by splitting and attenuating the optical power across multiple fibers. Using FBT and PLC technologies that are GR1209/1221 compliant, Clearfield offers split ratios from 1:2 up to 1:64. Custom attenuation ratios on outbound legs of the splitter can be configured to vary depending on network needs.
From the central office out to the fiber distribution hub and the network access point, splitters are used throughout an FTTH network. They are integrated into packaging systems that are specific to manufacturers and depend on the specified architecture.
Splitters can incorporate WDM functionality in a 2 ×16/32 package, allowing for redundancy or wavelength splitting such as is used in an RF overlay environment in a PON deployment. They are used in HFC networks for signal splitting to multiple receiving sites, and for signal coupling in return patch combining networks.
