Finisar introduces next generation 100G serial QSFP28 and ‘industry first’ 50G SFP56 transceivers
Finisar has introduced a 100G serial FR transceiver in the popular QSFP28 form factor for inter-data centre, transport and router applications with 2km reaches. Previewing at the OFC 2018 conference and exhibition in San Diego, the module leverages a standard 4x25G electrical interface, so that it plugs into standard QSFP28 slots, but employs just one serial 100G PAM4 optical channel. Once deployed in sufficient volume, it is expected to replace existing 100G QSFP28 CWDM4 modules. The company also plans to introduce a 500m DR version of this module. Four of these FR or DR modules will be able to be used in a fan-out configuration with an IEEE standard 400G DR4 module, thus providing both 100G point-to-point and 100G-to-400G fan-out connectivity at 100G per lane.
Enabling the next generation of 50G single-lane optical connections, the company introduced – and demonstrated – at the same time, what it says is the industry’s first 50G SFP56 SR and LR transceivers, using serial PAM4 technology. These modules represent the next key step in the highly popular SFP+ family of optical modules that have become ubiquitous in worldwide enterprise, data centre and service provider networks. Primary applications for these products include server-to-switch and switch-to-switch 50G Ethernet connections, and future 5G wireless applications.
Leveraging in-house vertically integrated optics and IC’s, these modules support interoperability with previous generations of 25G SFP28 and 10G SFP+ optical transceivers. Both modules comply with the corresponding 50GBASE-R specifications as defined in the IEEE standards and offer 50G PAM4 electrical and optical interfaces.

Emtelle expands PowerProtect+ portfolio with new end-to-end solution for data centres
Emtelle has a new addition to its PowerProtect+ range with Opticom, which was recently chosen as the new standard duct between manholes and intake areas of a range of data centres in EMEA. Launched at this year’s Data Centre World exhibition, the product features an IP57 watertight seal to create a dedicated pathway for each cable inside its own sub-duct, protecting it from water and dirt ingress. When combined with the firm’s PowerProtect+, it creates a dedicated pathway for communications and power cables. These pathways can withstand temperatures as high as 75°C when exposed to heavy loads. Opticom has been developed for use in data centres worldwide. Its rugged design and PVC
Corning TXF optical fibre allows high data-rate transmission over longer spans
Corning’s latest optical fibre launch – Corning TXF fibre – enables high data-rate transmission over longer spans and extended reach for improved network flexibility. The ultra-low loss, silica-core fibre with large
effective area, is ITU-T G.654.E compliant, highlighting the industry’s recognition of the value that large effective-area fibre can bring to the terrestrial market.

build provide the strength to withstand the most common causes of damage in cable installations. Each individual sub-duct is colour-coded to ensure installation takes place inside the correct pathway, while spare sub-ducts and the outer housing of the Opticom duct can also be sealed at any presentation points, ensuring a clean and clear pathway for future cable installation. The PowerProtect+ range features an
interference ring seal designed for easy power cable placement, allowing smooth and safe cable passage. The inner ducts come in four different colours, making sure that every duct is attached to the correct sub-duct, enabling smooth and efficient installation. This allows swift identification between various uses for ducts, including FTTx, low voltage, medium voltage and fibre.

The company presented a joint research paper with BT at the OFC 2018 Technical Symposium. The paper describes a detailed study comparing the performance of TXF fibre to standard single-mode fibre for operation of 400G single-carrier transmission in an ultra- spectrally efficient 1.2 Tb/s superchannel. The study demonstrates the capability of TXF fibre to suppress non-linear signal distortion, thereby extending reach through a combination of higher allowable launch power and lower loss.
