- Converts 10-, 100-, or 1000-Mbps copper to 1000-Mbps multimode fiber operating at 850-nm wavelength.
- True Layer 2 media conversion.
- Work with High-Density Media Converter System II Chassis.
This Layer 2 media converter is a switch that actively stores, filters, and forwards Ethernet packets for maximum network efficiency. It works with High-Density Media Converter System II. High Density Media Converter System II Layer 2 Module, 10BASE-T/100BASE-TX/1000BASE-T to 1000BASE-SX, belongs to a large family of modular media converter and communications options that provide an exceptional range of choices for your managed enterprise network. With more than 100 modules to choose from, this system can adapt to even the most demanding network configurations. All media converter modules are hot-swappable—you never need to power down a chassis to change a module.
High-Density Media Converter System II is particularly well suited for network-extension applications, offering a wide range of hot-swappable media converter modules for network extension over fiber. Additionally, the system offers a range of modules such as T1/E1, VDSL, and ATM that are not usually available with chassis-based media converter systems.
Unlike Layer 1 media converters, which only convert one Ethernet media type to another, Layer 2 modules for the High-Density Media Converter System II are true switches—they actively store, filter, and forward Ethernet packets like any other MAC-layer switch.
Layer 2 media converters increase network efficiency and reduce network overhead, significantly increasing data throughput.
Because Layer 2 media converters are also switches, they incorporate 10/100 or 10/100/1000 ports in contrast to the single-speed ports of Layer 1 converters. You can set the RJ-45 ports for autonegotiation or set them for 10-, 100-, or 1000-Mbps speed as well as for half- or full-duplex. The fiber port can be set for half- or full-duplex, too.
Additionally, the module features Link Fault Pass Through (LFPT), which is a troubleshooting feature that combines TX and FX LinkLoss from the local and remote devices. With LFPT enabled, when a link fault is sensed, it will pass through the device at each segment. In this way, both switches are alerted to a fault in the line, and they will send out traps. The SNMP server receives the traps and takes appropriate action to remedy the situation (usually by alerting a network administrator).
The 10BASE-T/100BASE-TX/1000BASE-T to 1000BASE-SX module featured here provides short-range Gigabit Ethernet connections of up to 550 meters (1804.4 ft.). The 10-/100-/1000-Mbps ports on the copper side are auto sensing.
