Small Form-factor Pluggable (SFP) is a compact, hot-pluggable network interface module format used for both telecommunication and data communications applications. An SFP interface on networking hardware is a modular slot for a media-specific transceiver, such as for a fiber-optic cable or a copper cable. [1]
A 10GBASE-SR SFP+ transceiver. 10GBASE-SR ("short range") is a port type for multi-mode fiber and uses 850 nm lasers. [28] Its Physical Coding Sublayer (PCS) is 64b/66b and is defined in IEEE 802.3 Clause 49 and its Physical Medium Dependent (PMD) sublayer in Clause 52. It delivers serialized data at a line rate of 10.3125 Gbd. [29]
XFP is a slightly larger form factor than the popular small form-factor pluggable transceiver, SFP and SFP+. ... SR - 850 nm, for a maximum of 300 m; LR - 1310 nm ...
The interconnection between this 'remote line card' and the 5000 or 7000 parent switch uses either proprietary interfaces (CX-1 for copper or the short or long range Cisco Fabric Extender Transceiver (FET) interfaces), or standard interfaces (Cisco SFP+ SR and LR fibre interface modules or SFP+ Twinax cables). In combination with the 5000/6000 ...
The 10 Gbit/s Ethernet Passive Optical Network standard, better known as 10G-EPON allows computer network connections over telecommunication provider infrastructure. The standard supports two configurations: symmetric, operating at 10 Gbit/s data rate in both directions, and asymmetric, operating at 10 Gbit/s in the downstream (provider to customer) direction and 1 Gbit/s in the upstream ...
Generally, layers are named by their specifications: [8] 10, 100, 1000, 10G, ... – the nominal, usable speed at the top of the physical layer (no suffix = megabit/s, G = gigabit/s), excluding line codes but including other physical layer overhead (preamble, SFD, IPG); some WAN PHYs (W) run at slightly reduced bitrates for compatibility reasons; encoded PHY sublayers usually run at higher ...
North Korea condemned on Saturday recent joint military drills by the United States, South Korea and Japan, warning that it would take immediate actions if needed to defend the state. Last week ...
