Applications

Typical applications include extending SDH/SONET backbones and adding Ethernet service to existing T1 or E1 fiber optic links. Service Providers use the TC8516 as an efficient, cost effective method to provide their customers with Ethernet (full 100 Mbps bandwidth) connections for data and T1 for voice. The two-way “one fiber,” option can double usage of existing fiber optic cable plants.

Description

The TC8516 Ethernet & T1/E1 Fiber Multiplexer multiplexes 8 or 16 T1 or E1 channels and one 10/100 Ethernet channel over multimode and single mode fibers.

The TC8516 supports distances to more than 100 km and offers a two-way, "one fiber" communication option to maximize fiber cable usage. Standard redundant power and optics include automatic switchover for maximum reliability.

Setup, diagnostics and control is accessed via Serial Console, Telnet or SNMP management ports. Diagnostics include LED indicators, dry contact alarms and local and remote loopback.

The Ethernet port supports non-blocking full 100Mbps bandwidth. It is IEEE 802.3/802.3u/802.3x compliant. Each T1 or E1 channel is independent, transparent to the framing format and supports all applicable standards and line codes.

The TC8516 is available in 1U high “Rack Mount.” Fiber optic connectors are SC. Standard power is 110/230VAC, 24VDC or -48VDC with hot swappable redundant power supply slot.
