Sumitomo Electric expands module line

Sumitomo Electric Industries, Ltd. (TOKYO: 5802) (ISIN: JP3407400005) will unveil three new optical modules during OFC/NFOEC this week at booth #1624. The modules address 40-Gbps and 100-Gbps applications.

Sumitomo Electric Industries, Ltd. (TOKYO: 5802) (ISIN: JP3407400005) will unveil three new optical modules during OFC/NFOEC this week at booth #1624. The modules address 40-Gbps and 100-Gbps applications.

Sumitomo Electric will debut two 40-Gbps devices The first, a 40G-LR4 QSFP+, targets data centers that use multiple tiers of networks to aggregate and link traffic. The QSFP+ format offers improvements in real estate, power, and port density over typically larger modules now in use. The new device complies with the QSFP+ Multi-Source Agreement (MSA), consumes a maximum of 2.5 W, and will support both IEEE802.3ba (40GBase-LR4) and ITU-T G.695 (OTU3) operation over as much as 10 km via standard singlemode fiber. Sumitomo will demonstrate the QSFP+ using an IXIA QSFP+ load module.

The other 40-Gbps module is what Sumitomo Electric asserts is the first 40G-FR CFP for 2 km applications. It is enabled via Sumitomo Electric’s high speed 40-Gbps electro-absorption modulator integrated laser diode for the optical transmitter and a high-speed PIN photodiode for the optical receiver. The 40G-FR CFP can support both IEEE 802.3bg (40GBase-FR) and ITU-T G.693 (OTU3); its maximum power consumption is compliant with CFP MSA power class 2.

The CFP demonstration will use the Anritsu MD1260A test instrurment for 40GbE. Sumitomo Electric has already released the 40GbE CFP optical transceiver for 10-km (40G-LR4) and 40-km (40G-ER4) reach. The 40G-FR CFP modules are shipping now with mass production planned for the second quarter of 2012.

At 100 Gbps, Sumitomo Electric will have a new 100G-LR4 CFP Low Power module for singlemode fiber connections of up to 10 km. The new module incorporates a CMOS-based Gearbox IC that requires only about two-thirds of the current 100G-LR4 CFP (maximum 16 W), the company says. The 100G-LR4 CFP modules offer customers IEEE802.3ba (100GBASE-LR4) and ITU-T G.959.1 (OTU4) connectivity options for data center, enterprise wiring closet, and service provider transport applications.

The company also will display its 10-Gbps DWDM and CWDM transceivers in the SFP+ form factor. The SFP+ transceivers can be used in metro and other telecom markets and include Limiting/Linear 80-km DWDM and 40-km/70-km CWDM SFP+ modules.
