The MGB family consists of Small Form Factor Pluggable (SFP) transceiver modules that are specifically designed for high performance integrated duplex data link over single mode optical fiber. These transceiver modules are compliant with the SFP Multisource Agreement (MSA) and hot pluggable. These modules offer an easy way to be installed in SFP MSA compliant ports at any time without the interruption of the host equipment operation. The MGB family of SFP Mini-GBIC Gigabit Ethernet modules can be installed in PLANET Switch products with SFP mini-GBIC interface. The deployment distance can be extended from 100 meters (TP), 550 meters (Multi-Mode, LC), and up to 120 kilometers (Single-Mode, LC).
To meet the increasing demand of the Industrial Ethernet fiber solution, Planet releases the MGB-T series 1000Base-SX / LX transceivers that can operate reliably in electrically harsh, climatically demanding, and wide temperature range (-40°C to 75°C) environment. The MGB-T series 1000Base-SX / LX transceivers provide easy and fast 1000Base-SX / LX connection for Planet wide temperature industrial equipment. • Complies with the IEEE 802.3 ab / 802.3 z Gigabit Ethernet standard • 1 X 1000Mbps TP/ LC fiber port • Industry standard small form pluggable (SFP) package (for model MGB-TSX / MGB-TLX / MGB-TL30 / MGB-TL70) • Duplex LC connector • Differential PECL inputs and outputs • Single power supply 3.3V • TTL signal detect indicator • Hot Pluggable • Class 1 laser product complies with EN 60825-1 • Plug and Play Installation • -40 to 75 degrees C operating temperature for MGB-TSX / MGB-TLX / MGB-TL30 / MGB-TL70 PHY Type IEEE 802.3 z 1000Base-LX Fiber Type Single Mode Connector LC Wavelength 1310nm Maximum Distance 10km Operating Temperature -40 ~ 75 degrees C

LOADING...
The PLANET MGB-TLX is a 1 Gbps 1000BASE-LX SFP mini-GBIC transceiver for network administrators extending a compatible SFP-equipped switch over single-mode fiber links up to 10 km.
Recommended For
- Industrial network operators linking switches or media converters over single-mode fiber in locations exposed to a wide temperature range.
- Network technicians connecting compatible 1GbE SFP equipment across a single-mode fiber link of up to 10 km.
- Teams extending a wired network between remote buildings, equipment rooms, or industrial sites where a copper Ethernet run is unsuitable and single-mode fiber is already available.
- PLANET equipment maintainers who need a 1000BASE-LX SFP option for a compatible SFP port and can verify the host device supports this module.
Real-World Use Scenarios
- Connecting two buildings across a campus: Install compatible 1000BASE-LX SFPs at both ends of a single-mode fiber run to carry a gigabit Ethernet link between buildings, avoiding a long copper run.
- Extending a campus or office backbone to a distant network closet: Use the module with single-mode fiber to link SFP-equipped switches; the result is a 1 Gbps fiber uplink, provided the equipment and optics at both ends are compatible.
- Reusing installed single-mode fiber for a gigabit link: Where the fiber path and SFP ports are suitable, this module can connect network equipment without replacing the fiber plant; confirm the fiber connectors and transceiver compatibility before installation.
- Linking equipment in an industrial or temperature-variable location: In a compatible PLANET industrial switch or media converter, the wide-temperature version is intended to keep a single-mode gigabit fiber link operating in environments beyond typical indoor equipment-room conditions.
