Cisco – SFP (mini-GBIC) transceiver module – 1GbE

This makes it a highly versatile and cost-effective solution for short-distance network links, particularly within wiring closets, data centers, or office environments where fiber optic cabling might be impractical or unnecessary.

Key Features and Operating Principles:

• The “TE” in GLC-TE signifies its compliance with the IEEE 802.3ab 1000BASE-T standard. Consequently, it supports Gigabit Ethernet speeds (1 Gbps) over copper twisted-pair cabling. It’s important to note, however, that while it uses an RJ-45 connector, it does not support 10 Gigabit Ethernet speeds; it is purely a 1 Gbps module.
• This SFP module features a standard RJ-45 connector, allowing it to interface directly with commonly available Ethernet cables. Therefore, it’s ideal for leveraging existing copper infrastructure.
• A key differentiator for the GLC-TE (compared to its predecessor, the GLC-T) is its support for an extended operating temperature range, typically from -5°C to 85°C (23°F to 185°F). This enhanced capability makes it suitable for deployment in a wider variety of environmental conditions, including those that may not be strictly temperature-controlled, such as certain industrial settings or outdoor cabinets (when housed in appropriate enclosures).
• Furthermore, it features Auto MDI/MDIX, which automatically configures the transmit and receive pairs, eliminating the need for crossover cables.
• The “E” or implied “D” in GLC-TE (depending on specific Cisco documentation) typically indicates that it includes Digital Optical Monitoring (DOM) capabilities. This allows network administrators to monitor key operational parameters, such as temperature and power levels, thereby aiding in troubleshooting and proactive network management.
• It fully complies with IEEE 802.3ab and the SFP Multi-Source Agreement (MSA), ensuring broad interoperability with various networking equipment.
