Finding a problem before it becomes a hard failure does more than just prevent loss of service, it affords service providers sufficient time to address the problem appropriately. With troubleshooting often posing a large, time-consuming expense, service providers have discovered new methods for nonintrusive test access of fiber circuits. A value-added module (VAM) system equipped with monitor modules provides more flexibility and functionality in a variety of monitoring applications. Customer Premises Module Applications A customer premises VAM can be used as a demarcation point for subscribers requiring fiber feeds. The module slides into a fiber frame and fiber jumpers are subsequently installed from each module to the network equipment. Equipped with separate ports for local testing, the module uses splitters to route a portion of the transmit and receive signal to a monitoring port. Technicians then test the signal routed to the port via an external test device. This allows technicians access to both directions of the signal without disrupting service to the customer (see figure 1).

Technicians connect the two by installing fiber patch cords between the connector module and the monitor module, completing the cross-connect. The dual monitor module offers another economical method of providing nonintrusive access to fiber circuits. Dual monitor modules are used in cross-connect configurations in which the outside plant cables are terminated to standard bulkhead adapters and fiber optic terminal equipment cables are terminated at the rear of the monitor module (see figure 2). When the outside plant bulkhead terminations on the front are cross-connected to the fiber optic terminal monitor module, access is gained to both the transmit and receive signals of the circuit and monitoring can be performed without disruption to service.

Value-added modules (VAMs) equipped with optical splitters can cost-effectively distribute signals to multiple subscribers. The modules provide operators with unmatched flexibility and functionality. Splitting Up is Easy to Do A VAM splitter module allows service providers to transport a signal from the serving office to the far end of the network over one fiber before splitting the signal to feed multiple subscribers. The signal travels from the headend to a node site, where it is split multiple times via a predetermined split ratio. The subsequent signals are then sent downstream to subscribers (see figure 1).

A VAM splitter module includes separate ports for local testing. When providers split a signal, 90 to 95 percent of the signal is allowed to proceed to its destination and the remaining portion is sent to the local access port to be monitored or tested by an external test device. VAM splitter modules offer providers a wide range of split ratios to accommodate specific application requirements. The ability to easily monitor both directions from both ends of a fiber span greatly reduces the time necessary to locate failures or degradation points. Value-Added Functionality VAM splitter modules can be tailored to meet application requirements. Modules include most industry- standard singlemode and multimode connectors and module inputs and outputs are made via adapter, pigtail or bare fiber depending on requirements (see figure 2). Various combinations of all front access to input/output ports or rear access to both input/output ports are also available. All bare fiber options use 2.0 mm jacketing. The variety of module configurations allows service providers the opportunity to determine the number and type of optical connections necessary depending on whether a cross-connect or interconnect arrangement is used. 4 / 0 7 • 1 0 1 6 6 3 A E Value-Added Module System 4 w w w . a d c . c o m • + 1 - 9 5 2 - 9 3 8 - 8 0 8 0 • 1 - 8 0 0 - 3 6 6 - 3 8 9 1 WDM and CWDM Modules Overview Wavelength division multiplexing (WDM) remains the prevailing technology for adding flexibility and functionality to today’s optical networks. By transmitting signals at different wavelengths through the same fiber, WDMs can multiply transmission capacity, improve testing, and transmit voice services over video. Value-added module (VAM) systems equipped with WDM technology are used in a variety of applications to reduce operational expenses and increase revenue opportunities. Increasing Transmission Capacity Fiber overlays can be expensive and time consuming. In order to deliver broadband services, many service providers are integrating wavelength division multiplexing technology modules into the network to gain capacity without deploying additional fiber. Adding a WDM on each end of a circuit instantly doubles the bandwidth on a fiber pair. A typical application features one fiber for the transmit direction and another fiber for the receive direction (see figure 1). In these cases, it is simply a matter of incorporating a WDM module at each end of the span and adding new equipment transmitting at 1550 nm. The 1550 signal will travel on the same fiber, allowing the fiber plant capacity to double (see figures 2 and 3). The WDM approach also enables providers to work with existing electronic equipment, which proves to be a cost-effective solution. Coarse wavelength division multiplexer (CWDM) modules operate in a similar fashion to WDM, but allow for the addition of 8 or 16 additional signals to be transmitted over a single fiber. This is done by dividing the 1550 nm window into eight 20 nm spaced channels. CWDM electronics require the use of more precise and expensive lasers, but this cost can often be justified by the avoidance of costs associated with installing new fiber cables. 1310 FOT 1310 1310 Single Fiber Near End Far End Tx Rx 1310 FOT Tx Rx Figure 1 Original Network 1550 Near End 1310 FOT Tx Rx WDM Module WDM 1550 FOT Tx Rx WDM Module WDM Far End 1310 FOT Tx Rx WDM Module WDM 1550 FOT Tx Rx WDM Module WDM 1310 Single Fiber Single Fiber 1550 1310 Figure 2 Higher Capacity Network with WDMs Applications Near End Single Fiber CWDM Module Far End 1471 nm 1491 nm 1511 nm 1531 nm 1551 nm 1571 nm 1591 nm 1611 nm CWDM Module 1471 nm 1491 nm 1511 nm 1531 nm 1551 nm 1571 nm 1591 nm . 1611 nm Tx CWDM CWDM Rx Figure 3 Higher Capacity Network with CWDMs 4 / 0 7 • 1 0 1 6 6 3 A E Value-Added Module System 5 w w w . a d c . c o m • + 1 - 9 5 2 - 9 3 8 - 8 0 8 0 • 1 - 8 0 0 - 3 6 6 - 3 8 9 1 WDM and CWDM Modules Nonintrusive Testing Often, access to the customer or co-location site is restricted. With wavelength division multiplexers (WDMs), a signal at a different wavelength from the normal traffic is injected at the near end of a system and travels to the far end, where it is looped back via a WDM at the demarcation point and returns to the original end. This allows full bi-directional OTDR (optical time domain reflectometer) testing on a live transmit/receive pair to be conducted from a central location. The service provider reduces operational expenses by not rolling a truck to the far end or disrupting customer’s service for testing purposes. WDM modules allow out-of-band testing by enabling networks to operate and test at different wavelengths. A network operating at 1310 nm can be tested at 1550 nm or a network operating at 1550 nm can be tested at 1625 nm using a WDM module. Course wavelength division multiplexing (CWDM) networks allow out of band testing by designating one channel as the test channel. Out-of- band testing is a simple, effective solution that is easy to implement into the network (see figure 4).

In most applications, a 1310 nm fiber route has already been established to accommodate traditional voice grade service. By using a 1550 nm video transmitter, both video and voice co-exist on the same fiber pairs, but are independently delivered to the subscriber. Value-Added Functionality ADC’s plug-in value-added modules (VAMs) can be purchased with most industry-standard singlemode connectors. Module inputs and outputs can be made via adapter, pigtail or bare fiber depending on customer requirements (see figure 5). Various combinations of all front access to input/output ports or rear access to both input/output ports are also available. All bare fiber options use 2.0 mm jacketing. The variety of module configurations allows the provider the opportunity to determine the number and type of optical connections necessary depending on whether a cross-connect or interconnect arrangement is used in the fiber cable management scheme.
