3. Introduction
3-1 1-Port 1000Base-T SFP Mini-GBIC
Module - MGB-GT
Features:
● Comply with IEEE 802.3ab Gigabit Ethernet standard
● 1 x 1000Base-T port (RJ-45 connector)
● Up to 100m over 4-pair UTP Cat.5/5e cable
● Plug & Play Installation

3-2 1-Port 1000Base-SX / LX SFP Mini-GBIC
Modules - MGB-SX / MGB-LX / MGB-L30
/ MGB-L50 / MGB-L70 / MGB-L120
Features:
● Comply with the IEEE 802.3z Gigabit Ethernet stan
-
dard
● 1 x 1000Mbps LC fiber port
● Plug and Play Installation
● 0 to 50 Degree C operation temperature
Note
The MGB-L30, MGB-L50, MGB-L70 and
MGB-120 SFP transceivers provide the
optical power budget from 19dB to 30dB.
When shorter distance of single-mode fiber
cables is used, you might need to insert
an in-line optical attenuator in the link to
avoid overloading of the transceiver.

Note
1. The fiber connector and distance
support will be different by various
models.
2. The MGB-LAxx / LBxx should runs in
pair. It means you must connect MGB-
LAxx in one end and another MGB-LBxx
in the other end, for example LA10 to
LB10 where only one single mode optic
wire is required.
3. The MGB-LA10, MGB-LB10, MGB-LA20,
MGB-LB20 and MGB-LA40, MGB-LB40
SFP transceivers provide the optical
power budget from 12dB to 20dB.
When shorter distance of single-mode
fiber cables is used, you might need
to insert an in-line optical attenuator
in the link to avoid overloading of the
transceiver.
