Transition Networks Debuts 100G QSFP28 Transceivers
Emtelle’s 24-fibre bundle a ‘game changer’
Edge connectivity solutions vendor Transition Networks, has announced the release of a new family of 100G QSFP28 optical transceivers (TN- QSFP-100G Series) designed for data intensive 100 Gbps Ethernet networks. As data centre operators upgrade access switch links to 10 Gigabit Ethernet (10 GbE), there is a growing demand for 100 GbE aggregation links to core switches. Transition Networks says its QSFP28 optical interfaces are the most compact 100 GbE pluggable interfaces on the market, resulting in higher port-density switches that are ideal for this application. The TN-QSFP-100G Series of 100G optical transceivers are designed to install in any QSFP28 switch port. The TN-QSFP-100G- LR4 supports the 100GBase-LR4 standard for single-mode fibre and features standard AFL is launching the CGM™Plus high- density rack-mount panel designed for Wavelength DivisionMultiplexing (WDM) applications. The panel features galvannealed steel construction with a hinged tray system that extends from the front of the panel, and folds out of the way for unobstructed access. The CGM Plus panel can hold LGX® and Card Guide Modules (CGM™) devices interchangeably. Designed for high density applications, CGM panel-mount WDM devices are pre-terminated plug-and-play products built for space efficient design. Using proven thin-film filter technology, CGM devices feature low insertion loss, high isolation and superior environmental stability. Available with up to 40 DWDM channels, CGM devices can also be configured with optional express, upgrade or test ports. “Headend space has become increasingly
duplex LC connectors. The transceiver has a transmission distance of up to 10km over structured single mode fibre. The transceiver converts four input channels of 25 Gbps data to four channels of LAN WDM optical signals and then multiplexes them into a single channel for 100 Gbps optical transmission. The receiver side device de-multiplexes the WDM input into 4 optical signals. The TN-QSFP- 100G-CWDM4 has a transmission distance of up to 2 km over single mode fibre. For shorter range networks, the TN-QSFP- 100G-SR4 supports the 100GBase-SR4 standard and is compatible with OM3 (for distances up to 70 meters) and OM4 (for distances up to 100 meters) categories of multimode fibre. This transceiver also multiplexes four 25 Gbps data lanes into a single channel for 100 Gbps transmission.
Provider of blown fibre and ducted network solutions for the telecoms industry Emtelle, has launched a 24-fibre bundle solution which it says delivers significant cost savings and operational benefits for telecom operators. The new 24-fibre bundle solution forms part of Emtelle’s FibreFlow microduct system and has been launched in response to the growing pressure on operators to provide greater capacity over fibre. The solution adds extra capacity for up to 288 fibres in a 24-way tube bundle, and doubles the capacity of 3.5 and 4.0 mm microducts, reducing the need for so many feeder cables. “FTTx is growing rapidly around the world and more and more fibre is needed in networks which is exactly why we have launched the 24-fibre solution,” said Colin Kirkpatrick, European Business Development at Emtelle. “The new 24-fibre bundle solution is going to be a game-changer for the blown fibre industry. It is going to enable operators to install a 24-fibre bundle into their existing infrastructure to feed the wider areas of their FTTH deployments. In other words, existing operators using Emtelle microducts can double their capacity overnight and halve the blowing cost per fibre.” Emtelle’s 24-fibre bundle can be blown up to 600 metres into existing networks of underground tube bundles when using Emtelle’s GS150 blowing machine. It can be blown in either 3.5 mm, 5 mm or larger tubes while its low friction outer jacket allows fibre to be blown around bends effectively. This is designed to open up further opportunities for the solution to be deployed in locations where fibre installations were previously limited due to physically challenging terrain.
AFL WDM-enabled rack-mount high-density panel
congested as more and more equipment is required to meet the demands of customers,” explained Tom Jeffers, Product Manager for AFL. “The CGM Plus provides a high-density rack- mount solution using AFL’s Card Guide Modules and the added flexibility of being backward compatible with legacy LGX products. This not only reduces space, but gives customers a seamless upgrade path toward small form factor DWDM products.”
