PRODUCT FOCUS
Finisar recently announced that it is in full production of its 100G SWDM transceiver, which will be the first mass produced module capable of transmitting 100 Gbps over a single pair of multimode fibres and the first transceiver compliant with 100G SWDM4 specifications defined by the SWDM multi-source agreement (MSA). Many data centres carry 10 Gbps optical signals over duplex multimode fibre (MMF), where one fibre is used to transmit a signal and the other is used to receive a signal, but when upgrading to 40 or 100 Gbps over MMF, data centre operators need four times this number of fibres deployed if they want to use optical transceiver modules based on the IEEE 40GBASE-SR4 or 100GBASE-SR4 standards, with both relying on four fibre pairs. The transceiver, system, and cabling suppliers that constitute the SWDM MSA have agreed on specifications that avoid the need for this additional fibre, allowing data centres to further leverage investment in their existing MMF plant. Finisar was the first optical transceiver vendor to complete reliability testing and release a 40 Gbps SWDM4 module earlier this year and will now also become he first vendor to complete reliability testing and release a 100 Gbps SWDM4 module. “Finisar’s SWDM modules are the first of their kind to finish qualification and be released to mass production,” said Dale Murray, principal analyst at LightCounting Market Research. “These duplex MMF modules provide systems vendors with a strong competitive advantage against other vendors who o er only parallel multimode optics at 40G and 100G to their data centre customers.” In addition to the 40G SWDM4 and 100G SWDM4 modules currently in production, Finisar previously demonstrated an extended- reach 100G eSWDM4 module at ECOC 2017. Both 40Gb/s and 100Gb/s modules comply with SWDM MSA specifications. Finisar starts 100G SWDM4 QSFP28 production
Push-fit solutions for blown fibre installations
John Guest’s push-fit range has been built to perform in challenging conditions in local loop, network and NGA applications. The range o ers solutions for both blown fibre and cable pressurisation systems, in aerial and underground deployments. A specialised range for gas and water blocking is also available. For direct buried
applications, John Guest o ers a ‘Speedfit Secure’ range, which features an integral collet-locking mechanism to provide additional security. Making a connection using the company’s Speedfit technology is as simple as pushing the transport duct into the connector. The unique collet locking mechanism securely retains the duct whilst a radial sealing system enables pressurisation for blowing cables.
