Deployment / Use Cases
This SFP module is specifically designed for point-to-point fiber optic links in enterprise, service provider, and industrial networks. Its 40km reach makes it suitable for connecting geographically dispersed buildings, data centers, or network aggregation points.
Common applications include extending Gigabit Ethernet over existing single-mode fiber infrastructure, building redundant network links, and connecting remote switches or routers in campus environments. The module's bi-directional operation is particularly valuable in scenarios where fiber availability is limited or costly to expand.
Long-Distance Network Links
Connect switches or routers across campuses, industrial parks, or metropolitan areas using existing single-mode fiber runs.
Fiber Capacity Optimization
Maximize existing fiber infrastructure by transmitting and receiving data over a single strand instead of two separate fibers.
Physical Profile
The module follows the standard SFP form factor dimensions for seamless integration into SFP slots on compatible networking equipment. Its hot-pluggable design allows for installation or replacement without powering down the host device, minimizing network downtime during maintenance or upgrades.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 7" (177.80 mm), 9" (228.60 mm), 23" (584.20 mm), 12.65 lb (5737.94 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.

User Manual
FAQ
What is the maximum transmission distance of this SFP module?
The TRENDnet TEG-MGBS40D3 supports transmission distances up to 40 kilometers (approximately 24.85 miles) over single-mode fiber. This extended reach makes it suitable for connecting network equipment across campuses, between buildings, or in metropolitan area networks where longer fiber runs are required.
What type of fiber connector does this module use?
This module uses an LC simplex connector, which is designed for single-strand fiber connections. The LC connector type is compact and widely used in fiber optic networking, providing reliable performance with low insertion loss for optimal signal integrity over long distances.
What does 'bi-directional WDM' mean for this SFP module?
Bi-directional Wavelength Division Multiplexing (WDM) allows the module to transmit and receive data over a single strand of fiber using different wavelengths. The TEG-MGBS40D3 transmits at 1310nm and receives at 1550nm, effectively doubling the capacity of your fiber infrastructure by eliminating the need for separate transmit and receive fibers.
Is this SFP module hot-pluggable?
Yes, this module features a hot-pluggable form factor, meaning you can install or remove it from a compatible switch or router without powering down the equipment. This capability minimizes network downtime during maintenance, upgrades, or module replacement, supporting continuous network operation.
What compatibility standards does this module meet?
The module is Multi-Source Agreement (MSA) compliant, ensuring mechanical and electrical compatibility with a wide range of SFP-enabled networking equipment from different manufacturers. It also complies with IEEE 802.3z for Gigabit Ethernet and ANSI Fiber Channel standards, providing reliable interoperability in diverse network environments.
What is the pairing requirement mentioned for this module?
The TEG-MGBS40D3 must be paired with a compatible module at the opposite end of the fiber link, specifically the TEG-MGBS40D5 or another module with matching specifications. This pairing ensures proper wavelength alignment—with one module transmitting at 1310nm and receiving at 1550nm, and its partner doing the opposite—for successful bi-directional communication over a single fiber strand.
