High-Density Media Converter System II T1/E1/J1 to Duplex Fiber Module, Twisted Pair (RJ-48) to Multimode, 1300-nm, 2 km, SC
<b>Quick Facts</b>
- Convert T1/E1/J1 to multimode or single-mode fiber for extending copper-based circuits.
- Extend in interference-heavy areas—up to 2 kilometers (1.2 mi.) with the multimode models and as far as 80 kilometers (49.7 mi.) with the Long single-mode modules.
- Install in our High-Density Media Converter System II Chassis.
<b>Further Details</b>
These Physical Layer modules for the High-Density Media Converter System II belong to a large family of modular media converter and communications options for your managed enterprise network. With many modules to choose from, this system can adapt to even the most demanding network configurations.
They convert the incoming electrical signal from one cable type and then transmit it over another type. The media converters are totally transparent to network operation, having no effect on the data being sent across the link. What's more, all of the modules are hot-swappable—you never need to power down a chassis to change a module.
The High-Density Media Converter System II T1/E1/J1 to Duplex Fiber Modules featured here enable you to extend 1.544-Mbps T1/J1 or 2.048-Mbps E1 copper-based circuits over multimode or single-mode fiber optic cable. They're ideal for use with PBX systems or legacy telco circuits.
These modules are selectable to support 1.544-Mbps T1 (ANSI T1.403), 2.048-Mbps E1 (G.703), or 1.544-Mbps J1. Offering protocol-selectable operation, the converters enable you to easily choose between T1/J1 and E1 rates via DIP switches on their boards. Built-in jitter removal ensures maximum throughput.
The modules also feature full diagnostics, including three modes of operation for loopback testing (Fiber Analog Loopback, Fiber Digital Loopback, and Twisted-Pair Digital Loopback), a line integrity test feature, and a Transmit Data Source diagnostic feature. Manage the modules through an optional SNMP Management Module (LMC5200A) plugged into the High-Density Media Converter System II Chassis.
In addition, an MDI/MDI-X switch on the modules configures the RJ-48 port for crossover or straight-through cable connection automatically.
