## Summary description

QOLTEC Cable Patchcord Crossover CAT5E (model 52300) is a crossover Ethernet patch cable compliant with CAT5E standards for connecting network devices directly. It supports typical CAT5E performance for 100BASE-TX and Fast Ethernet linkups, with RJ45 terminations for direct device-to-device connections, testing, or temporary network reconfiguration.

## Long description

QOLTEC Cable Patchcord Crossover CAT5E (model 52300) is a 1.8 m UTP crossover Ethernet patch cable designed to connect two network devices directly without a hub or switch. Constructed to meet CAT5E performance parameters, the cable supports Fast Ethernet (100BASE-TX) linkups and typical CAT5E signal integrity. With standard RJ45 terminations and a crossover wiring scheme, it is suitable for direct device-to-device connections, short-term testing, and temporary network reconfiguration tasks.
Advantages
The crossover patch cord provides a ready-made solution for linking two endpoints such as computers, routers, or switches that require transmit/receive line swapping. Its CAT5E-rated twisted-pair construction ensures consistent impedance and reduced crosstalk compared with lower-category cables, while the 1.8 m length offers flexibility in typical desk- or bench-top setups. Standard RJ45 connectors give broad compatibility with network equipment that uses 8P8C ports.
Suitable for
 Direct connection of two computers or network devices without an intermediary switch
 Temporary network tests and diagnostics on Fast Ethernet links
 Connecting routers or switches in lab and field environments for configuration
 Short cable runs between devices on a desk, rack, or bench
Key specifications
 Category: CAT5E (unshielded twisted pair)
 Wiring: Crossover (swap of transmit and receive pairs)
 Connector type: RJ45 (8P8C) on both ends
 Length: 1.8 m
 Supported speed: Suitable for Fast Ethernet (100 Mbps) and typical CAT5E link performance
 Application environment: Indoor use for short network runs, testing, and configuration
How to use
Insert each RJ45 connector into the corresponding 8P8C port of the devices to be connected. Ensure devices are powered off or have link negotiation enabled if required by the equipment. After plugging in, check link LEDs or network settings to confirm a successful connection and proper link speed. For diagnostic tasks, use this crossover cable to establish a direct link between two devices for packet testing, configuration transfers, or temporary data exchange.
Usage recommendations
Use the cable for short, indoor connections and avoid running it near sources of strong electromagnetic interference. Do not bend sharply near the connectors; leave a small service loop to prevent strain. For permanent installations or longer runs, consider using straight-through CAT5E or higher-category cabling and proper structured cabling practices.
