Opnext announces production release of 40GBASE-LR4 CFP transceiver

Optical module and component maker Opnext Inc of Fremont, NJ, USA has announced the production release of its TRC5B20 40GBASE-LR4 CFP transceiver, a pluggable module capable of transmitting and receiving 40 Gigabit Ethernet (40GbE) and OTU-3 traffic over reaches of up to 10km on single-mode fiber.

Opnext says that the transceiver’s multi-rate and multi-protocol capability enables greater flexibility in system design for connecting high-speed switches and routers, as well as large data-centers where the 100m reach of multimode fiber is insufficient.

With the release of the IEEE-802.3ba standard published last June, interest in new 40GbE and 100GbE transceivers has increased dramatically, says Opnext, and system vendors are already working on releasing next-generation products supporting this standard.

The firm says that, using its expertise in developing low-power distributed feedback (DFB) lasers, the 40GBASE-LR4 transceiver design has uncooled CWDM (coarse wavelength-division multiplexed) DFB lasers that deliver superior performance while consuming less power. 40GBASE-LR4 technology offers OEMs a lower-cost, longer-reach alternative to traditional 40G Sonet/SDH client interfaces and makes 40G deployments even more economically viable in high-speed switches and edge routers, adds the firm.

*At this week’s Optical Fiber Communication Conference and Exposition and the National Fiber Optic Engineers Conference (OFC/NFOEC 2011) in Los Angeles (8–10 March), Opnext is displaying multiple demonstrations on the exhibit floor, including:

  • the first live technical feasibility demonstration of a CFP MSA (multi-source agreement) 100GBASE-ER4 client-side module running at 40km over single-mode fiber at OTU4 data rate (111.8Gbps);
  • a next-generation 300-pin 40Gbps DPSK line-side module in a 3.5” x 4.5” small form factor, suited to high-port-density applications (Opnext claims to be is one of the leaders in shipments of DPSK line-cards and line-side MSA modules);
  • the firm’s newest 40Gbps technology in a QSFP+ (quad small-form-factor pluggable plus) module — the QSFP+ 40GBASE-LR4 uses 4x10G CWDM integrated optics to transmit 40GbE traffic over 10km of single-mode fiber;
  • a tunable TOSA (of compact size for XFP module applications) showing wavelength tuning of an internally designed new tunable laser to deliver stable wavelength control.

Opnext is also participating in the Ethernet Alliance Interoperability demo (booth 1253), showcasing a live demonstration of some of the latest products developed for use in next-generation data centers.

In addition, Opnext display samples include the firm's 100Gbps DWDM single-wavelength PM-QPSK coherent module.

“Opnext continues to invest in the 40Gbps and 100Gbps products and technologies that will enable our customers to provide cost-effective networking solutions to their customers,” says chairman & CEO Harry Bosco. “Close partnerships with our customers are essential as we address the expanding bandwidth requirements and the technical challenges these requirements present in optical networking.”

Also, on Wednesday, 9 March, Opnext representatives are participating in the OFC/NFOEC conference program, including:

  • MarketWatch (1–3pm at the Expo Theatre I), ‘Panel III: 100G Ecosystem: Enabling Technology and Economics’, Ross Saunders (Opnext Subsystems);
  • Ethernet Alliance Panel (1–2pm at the Expo Theatre II), ‘Panel 1: The Future of Higher Speed Ethernet’, Jon Anderson (Technical Marketing);
  • Poster Presentation (10–12 noon, Exhibit Halls H & J), ‘Demonstration of World-First 103Gbits Transmission over 40km Single Mode Fiber by 1310nm LAN-WDM Optical Transceiver for 100GbE’.
