NEC Electronics Europe Announces New High-Operating-Temperature

1310nm TOSA for 10Gbit/s High-Speed Optical Transmission

DUSSELDORF (Germany), June 25, 2009 — NEC Electronics Europe introduces a new series of uncooled 1310nm Multiple Quantum Wells (MQW) structured Distributed Feed-Back (DFB) laser diodes allowing the operation up to 95°C and low power consumption. The NX8346-series transmitter optical sub-assembly (TOSA) is based on a new AlGaInAs chip design allowing high temperature and high speed operation. Due to an oxidation free BH-structure, low operating currents (Iop) and high reliability are achieved.

The NX8346-series TOSA is coming in a compact CAN package which is electrically isolated from the receptacle and integrates an InGaAs monitor PIN-PD. The receptacle is compatible with the small size LC optical connector making the NX8346-series TOSA ideal for installation into 10Gbit/s small form factor pluggable (XFP1/SFP+2) optical transceiver modules.

A small flexible printed circuit (FPC) which is attached to the stamp of the CAN package makes the electrical interface between the TOSA and the transceiver. To meet the different size requirements of XFP/SFP+ optical transceivers, there are two different FPC lengths available. The NX8346TB features a standard XMD-MSA3 compliant FPC which is suitable for XFP transceivers. To meet the reduced size requirements of SFP+ compliant transceivers the NX8346TY and NX8346TS TOSA utilize a short length FPC with 20% reduced size compared to the XMD-MSA3 compliant FPC.

Aiming the 10Gb/s Datacom and Telecom market, the NX8346-series TOSA are compliant with 10GBASE-LW/LR, 10G Fiber Channel and SONET OC-192 standards.

NX8346-series TOSA are coming with a lead-free internal optical isolator fully compliant with the latest requirements of RoHS directive for fiber optic communication systems.

The new 1310nm TOSA are in mass production and samples are available.

Notes:

1 XFP (10 Gigabit Small Form Factor Pluggable) is a hot-swappable, protocol-independent optical transceiver, typically operating at 850nm, 1310nm or 1550nm, for 10Gbit/s SONET/SDH, Fibre Channel, 10Gbit Ethernet and other applications, including DWDM links. XFP employs a serial interface (XFI) and uses LC optical connectors.

2 SFP+ (10Gbit/s small form-factor pluggable) is a compact, hot-pluggable transceiver used for 10Gbit/s data communications applications (10GbE and Fibre Channel). In comparison to Xenpak, X2 or XFP type of Transceiver modules, SFP+ modules leave some of the circuitry to be implemented on the host board instead of inside the module.

3 A 10Gbit/s Miniature Device Multi-Source Agreement to establish compatible sources of 10Gbit/s Transmitter Optical Sub-Assembly (TOSA) and Receiver Optical Sub-Assembly (ROSA) for use in the 10 Gbit/s transceivers. This initiative standardizes the common mechanical dimensions, footprint and pin functions of the TOSA/ROSA devices.
