40G Transceiver Form Factors The QSFP+ form factor is specified for use with the 40 Gigabit Ethernet. Copper direct attached cable (DAC) or optical modules are supported, see Figure 85–20 in the 802.3 spec. QSFP+ modules at 40 Gbit/s can also be used to provide four independent ports of 10 gigabit Ethernet. [1] 100G Transceiver Form Factors
Cisco Paging Server (InformaCast) - Paging/bell/mass notification system for CUCM. Originally developed by Singlewire Software, sold as a Cisco product. [22] Cisco Unified Communications Manager Express (CUCME) - a small scale/single server contact center solution; Cisco Unified Operations Manager (CUOM)— a NMS for voice.
A ready-to-use module is a complete system with a transceiver, and optionally an MCU and antenna on a printed circuit board. While most of the modules in this list are Zigbee , Thread , ISA100.11a , or WirelessHART modules, some don't contain enough flash memory to implement a Zigbee stack and instead run plain 802.15.4 protocol, sometimes with ...
OC-768 SONET interfaces have been available with short-reach optical interfaces from Cisco since 2006. Infinera made a field trial demonstration data transmission on a live production network involving the service transmission of a 40 Gbit/s OC-768/STM-256 service over a 1,969 km terrestrial network spanning Europe and the U.S.
NG-PON2 (also known as TWDM-PON), Next-Generation Passive Optical Network 2 is a 2015 telecommunications network standard for a passive optical network (PON). The standard was developed by ITU and details an architecture capable of total network throughput of 40 Gbit/s, corresponding to up to 10 Gbit/s symmetric upstream/downstream speeds available at each subscriber.
An optical module is a typically hot-pluggable optical transceiver used in high-bandwidth data communications applications. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside world through a fiber optic cable.
The physical coding sublayer (PCS) is a networking protocol sublayer in the Fast Ethernet, Gigabit Ethernet, and 10 Gigabit Ethernet standards. It resides at the top of the physical layer (PHY), and provides an interface between the physical medium attachment (PMA) sublayer and the media-independent interface (MII).
The physical-layer specifications of the Ethernet family of computer network standards are published by the Institute of Electrical and Electronics Engineers (IEEE), which defines the electrical or optical properties and the transfer speed of the physical connection between a device and the network or between network devices.
