( Brand: Hp ), ( Manufacturer Part Number: 659580-001 ), ( Part Type: Plug Transceiver Module )
The 659580-001 and 10 661726-001 are identical 1GB SFP RJ-45 Plug-in Transceiver Modules, designed for use in data communications applications. These transceivers comply with the Small Form-factor Pluggable (SFP) standard, which defines a compact, versatile networking interface.
The module is a hot-pluggable transceiver, meaning it can be installed or removed from the network equipment without powering down the device. The SFP form factor offers extensive connectivity options, enabling compatibility with a variety of networks and infrastructure. In this case, the transceiver provides both 1GB Ethernet and RJ-45 interfaces, making it suitable for use in environments that require both SFP and RJ-45 cables.
The 1GB Ethernet interface operates at a data rate of 1 Gigabit per second, delivering high-speed data transfer with minimal latency. The RJ-45 interface incorporates an autonegotiating 10BASE-T/100BASE-TX Ethernet connector, enabling full-duplex, half-duplex, and auto-MDI/MDIX support. It's compatible with industry-standard RJ-45 cables, which are widely available for various uses in enterprises and home networks.
Key features include Data Transfer Rate up to 1Gbps (1000Base-T), Supports both 1000Base-T Full and 1000Base-T Half auto-negotiating options, and Wide operating temperature range of -10 C to 70 C. Additionally, these transceivers support various industrial and enterprise applications such as data centers, telecommunications, and service provider networks.
To sum up, the 659580-001 and 10 661726-001 are identical 1GB SFP RJ-45 Plug-in Transceiver Modules, which offer a compact, versatile connectivity solution for 1 Gigabit Ethernet networks. Their small form factor, advanced features, and industrial compatibility make them an excellent choice for various applications in data centers, enterprise networks, and service provider environments.
