JDSU DSAM-3500 Digital Service Activation Meter

The DSAM-3500 Digital Service Activation Meter is a lightweight, durable, handheld meter for installation and troubleshooting. It features an intuitive graphical interface complete with an informative online help system.
It provides traditional SLM test functions of analog video and audio levels and digital power levels. The video auto-test feature allows administrators to pre-program a test plan for multiple channels that a field technician can execute consistently with a single test selection. Additional features include a tilt screen and the Mini-scan feature; a simple one-key test that shows a summary of 1 to 12 channels. The DSAM-3500 has full DOCSIS® Service Verification and IP Performance tests with TruPacketTM. It also provides IP testing through the Ethernet jack. This series also includes a full downstream spectrum view as a convenient means of observing the carrier shape or checking for off-air forward ingress. Digital QAM carriers may be closely scrutinized with a constellation view, complete with zoom levels and display of level, MER/EVM and estimated pre and post FEC BER.

*This is a Web introductory price for one calibration of the JDSU DSAM-3500. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Bandwidth
Bandwidth is the difference between the upper and lower frequencies in a contiguous set of frequencies within which a fiber optic component, link or network will operate.

Multimode Fiber
Multimode Fiber has a large core (almost always 62.5 microns - a micron is one one millionth of a meter - but sometimes 50 microns) and is used with LED sources at wavelengths of 850 and 1300 nm for short distance, lower speed networks like LANs. Both multimode and singlemode fiber have an outside diameter of 125 microns - about 5 thousandths of an inch - just slightly larger than a human hair.

SDH
Synchronous Digital Hierarchy (SDH) is an international digital telecommunications network hierarchy which standardises transmission around the bit rate of 51.84 megabits per second, which is also called STS-1. Multiples of this bit rate comprise higher bit rate streams. Thus STS-3 is 3 times STS-1, STS-12 is 12 times STS-1, and so on. STS-3 is the lowest bit rate expected to carry ATM traffic, and is also referred to as STM-1 (Synchronous Transport Module-Level 1). The SDH specifies how payload data is framed and transported synchronously across optical fibre transmission links without requiring all the links and nodes to have the same synchronized clock for data transmission and recovery.
