What is QSFP+ cable?
QSFP also called QSFP+, it stands for Quad (4-channel) Small Form-factor Pluggable Optics Transceiver. It interfaces a network device (switch, router, media converter or similar device) to a fiber optic or copper cable.
What is inside a twinax cable?
An active Twinax cable has active electronic components in the SFP+ housing to improve the signal quality; a passive Twinax cable is mainly just a straight “wire” and contains few components….SFP+ Direct-Attach Copper (10GSFP+Cu)
| AWG cable size | Sustained bend radius |
|---|---|
| 30 | 0.9 inches (23 mm) |
What is SR4 and LR4?
The basic versions of QSFP are SR4 and LR4 that are respectively designed for MMF and SMF 40GbE applications. SR is short for short reach and LR represents Long Reach. 4 means 4 Tx and Rx. The interfaces designed by 40GBASE-SR4 and 40GBASE-LR4 are not the same.
What is the difference between QSFP+ and SFP+?
SFP+ vs QSFP+ The primary difference between QSFP and SFP is the quad form. QSFP+ is an evolution of QSFP to support four 10 Gbit/s channels carrying 10-Gigabit Ethernet, 10G Fiber Channel, or InfiniBand, which allows for 4X10G cables and stackable networking designs that achieve better throughput.
What is a passive twinax cable?
A passive twinax cable carries a signal over short lengths (5m or under) of copper with no additional components to boost signal. While an active copper cable contains electrical components in the connectors that boost signal levels.
What is SR4 cable?
40GBase-SR4 optics use a single MPO ribbon cable for both transmit and receive, as SR4 uses four strands for transmit and four strands for receive. Maximum distance depends on the type of multimode fiber used.
What is CSR4?
The plug-and-play Bluetooth CSR4. 0 USB Dongle helps you connect Bluetooth devices to your computer. With streamlined and minimalistic design, it won’t conflict with other USB devices in space. It works at low power consumption; supports Bluetooth voice data and multiple languages as well.
