GBIC Fiber Optics
A gigabit interface converter (GBIC) is a transceiver that converts electric currents (digital
highs and lows) to optical signals, and optical signals to digital electric currents. The GBIC is
typically employed in fiber optic and Ethernet systems as an interface for high-speed
networking. The data transfer rate is 1.25 gigabit per second.
GBIC modules allow technicians to easily configure and upgrade electro-optical
communications networks. The typical GBIC transceiver is a plug-in module that supports
hot-plugging (it can be removed and replaced without turning off the system). The devices
are economical, because they eliminate the necessity for replacing entire boards at the
system level. Upgrading can be done with any number of units at a time, from an individual
module to all the modules in a system. GBIC(Gigabit Interface Converter), meet the Gigabit
Interface Converter specification Rev. 5.4 (MOD_DEF4) industry standard.

3.Installation
Hardware Installation
This chapter describes how to install the VRM01/24. To established network connection.
You may install the VRM01/24 on any level surface (table, shelf, 19 inch rack or wall
mounting). However, please take note of the following minimum site requirements before
you begin.
Pre-Installation Requirements
Before you start actual hardware installation, make sure you can provide the right operating
environment, including power requirements, sufficient physical space, and proximity to other
network devices that are to be connected. Verify the following installation requirement:
Power requirements: AC 100V to 240 V at 50 to 60 Hz.
The Switch power supply automatically adjusts to the input voltage level.
 The VRM01/24 should be located in a cool dry place, with at least 10cm/4in of space at
the front and back for ventilation.
 Place the VRM01/24 out of direct sunlight, and away from heat sources or areas with a
high amount of electromagnetic interference.
 Check if network cables and connectors needed for installation are available.
General Rules
Before making any connections to the VRM01/24, note the following rules:
Ethernet Port (RJ-45)
All network connections to the VRM01/24 Ethernet port must be made using Category 5
UTP for 100Mbps and Category 3,4 UTP for 10Mbps.
No more than 100 meters (about 328 feet) of cabling may be use between VRM01/24s or
with HUB or an end node.
 VDSL Port (RJ-21)
All home network connections to the VDSL
1 X RJ-21 Cable (Male to Male)Using Pin 1 24.26 49.
RJ-21 Pin25 & 50 are not used.
Connecting the VRM01/24
The VRM01/24 has 2 x GIGA Ethernet Support full or half-duplex operation. The
transmission mode is using auto-negotiation. Therefore, the devices attached to these
ports must support auto-negotiation unless they will always operate at half duplex. If
transmissions must run at full duplex, but the attached device does not support
auto-negotiation, then you should upgrade this device to a newer version that supports

VDSL SERIES CTC Union
12
auto-negotiation.
Use “25” port connect to devices such as server, bridge or router. You can also cascade to
another compatible MUX or hub by connecting the 26 port to the other device.
“Port 25” support 10/100/1000Giga RJ-45/GBIC(fiber) Auto-Link. So you also can use Fiber
Optic wire connect to Port 25 GBIC side.
Connecting Ethernet Port
Ethernet Port “25” and “26” support auto MDI/MDIX.
You can connect the “25 or 26” port on the VRM01/24 to any device that uses a standard
network interface such as a Cable modem, ADSL modem, Ethernet Switch, workstation or
server, or also to a network interconnection device such as a bridge or router (depending on
the port type implemented).
Prepare straight through (or cross over) shielded or unshielded twisted-pair cables with
RJ-45 plugs on both ends. Use 100ΩCategory 5 cable for connections. Connect one end of
the cable to “25” port of the VRM01/24, and the other end to a standard RJ-45 station port
on cable modem, ADSL router, wireless bridge, etc. When inserting an RJ-45 plug, be sure
the tab on the plug clicks into position to ensure that it is properly seated.
Notes:
Make sure the length of twisted-pair cable is not over by 100 meters (328 feet).

VDSL Modem before making a connection to any of the VRM01/24 (1-24) station ports.
You also need to prepare 18 ~ 26 gauge one twist pair phone Line wiring with RJ-11
plugs at both ends.
2. Connect one end of the cable to the RJ-11 port of the Home Access network adapter,
and the other end to any available (1~24) station port on the VDSL. Every port
supports 10 Mbps connections. When inserting an RJ-11 plug, be sure the tab on the
plug clicks into position to ensure that it is properly seated.
Instead, use only twisted-pair cables with RJ-45 connectors that conform the FCC
standards.
Notes:
1. Be sure each twisted-pair cable (RJ-45) is not over 100 meters (328 feet).
2. VDSL port use 18 ~ 26 gauge phone wiring, 28 gauge or above is not recommended.
3. We advise using Category 5 cable for Cable Modem or router connections or to attach to
any high bandwidth device to avoid any confusion or inconvenience.
