Finisar to demo range of products at ECOC 2017


Demonstrations include first 100G QSFP28 eSWDM4 transceiver offering the longest reach in the industry for multimode fibre

Finisar has announced several product demonstrations taking place this week at ECOC, the European Conference on Optical Communications in Gothenburg, Sweden.

Demonstrations include the industry's first 100G QSFP28 eSWDM4 transceiver offering the longest reach in the industry for multimode fibre (MMF), a 10G tuneable BiDi transceiver for wireless, CATV and Enterprise networks, a 100G QSFP28 ER4f transceiver supporting 40km 4WDM applications, and two new members of the optical instrumentation family.

Finisar's 100G QSFP28 eSWDM4 transceiver is a new member of Finisar's suite of extended reach QSFP28 form factor modules. The eSWDM4 transceiver leverages Finisar's SWDM4 technology and enables 200, 300 and 400 meter links at 100G data rates over OM3, OM4, and OM5 duplex MMF, respectively. This module provides the longest fibre reach among duplex MMF solutions in the industry for 100G QSFP28 Ethernet applications. Duplex MMF is important because it allows datacentre operators to upgrade from 10G to 100G without installing additional fibre.

During the show, Finisar will demonstrate a QSFP28 eSWDM4 module transmitting live data over 300 metres of OM4 multimode fibre connected to a receiving QSFP28 eSWDM4 module. A network tester will display an error-free link using FEC (Forward Error Correction). This new transceiver offers the most cost-effective 100G solution for 300 meter links in the industry. It interoperates with standard reach 100G QSFP28 SWDM4 modules and can be used with existing duplex fibre infrastructure deployed for legacy applications, such as 10G.

First tuneable BiDi SFP+ transceiver

Finisar will also introduce what it believes is the industry's first tunable BiDi SFP+ transceiver for wireless and metro-access networks. The novel dual-band bidirectional DWDM architecture fits one pair of channels into a 100GHz band. It supports full C-band tunability with 40 bidirectional point-to-point links on a single fibre, increasing fibre capacity by a factor of 80 compared to "grey-optics" traditionally used to serve these network applications. It can also be used within existing 100GHz DWDM fibre plants.

This dual-band bidirectional DWDM architecture uses standard C-band optics and 100GHz Multiplexers and De-multiplexers without requiring cyclic AWG or L-band tunable lasers needed for conventional bidirectional DWDM solutions. In addition, it reduces the number of patch cables by a factor of two, simplifying field installation costs with fewer connectors. The proposed tunable BiDi SFP+ transceiver is the most fibre efficient and lowest cost 10G DWDM solution on the market for end-customers.

The live demonstration will include multiple tunable Bidi SFP+ modules supporting 40 bidirectional point-to-point links on a single fibre. A self-wavelength tuning feature using Finisar's Transceiver to Transceiver Digital Optical Communication (T2DOC™) channel technology will also be demonstrated.
