RLH-TG Mux RLH-TG Mux
Rx Tx can test T1/E1 connection cable, and Tx Rx is used to test the whole circuit including then
units at each end and the link between them.
Note: This equipment Ethernet electrical interface with the HP auto-MDIX feature that automatically
detect network cable transmitting/receiving sequence and then adapting, both of MDI and MDI-X
Ethernet interface, both crossover cable or straight cable can be used. Uplink interface connect with the
Ethernet interface of wireless bridge we need to use straight cable.
Warning: When connecting to a wireless LAN bridge, the uplink Ethernet cable often connects to the
outdoor unit, posing danger to lightning strikes that can seriously damage the equipment. To protect the
equipment as well as people, surge protection devices with good earth connection is strongly
recommended. Poor earth connection may also hinder the operation of the Ethernet port, causing
severe packet losses.
Ethernet/fiber optic connection
RLH-TG Mux provides 5 standard RJ45 Ethernet interfaces and an SFP optical transceiver interface for
connection with the transmission network, such as wireless Ethernet bridge interface, or access to a
local Ethernet port, such as switch and so on. Any Ethernet electrical interface can be used for Web
Server or SNMP management and device software and hardware upgrades.
The Ethernet optical interface uses SFP integrated optical modules. Dual fiber transceivers are marked
with for the optical signal input and with for the optical signal output. When connecting optical
fiber to the transceiver, roll the fiber connections by attaching the Tx connector from on end to the Rx
connector on the far end. Single fiber bi-directional transceivers are provided in pairs identified as C side
or S side.
Keep the SFP protection plug and optical optical fiber caps in place until installed to prevent
contamination.
Note: Fiber cable should always be routed loosely avoiding tight bends. Patch cord bend radius should
be no less than 50mm. The optical connector should not be pulling directly on the transceiver.
