September 16, 2005 Shenzhen, China -- With the FTTH market heating up in China, several companies from that country took advantage of last week's China International Optoelectronic Expo (CIOE) in Shenzhen, China, to show off their wares. Transceivers and passive devices were prominently on display.
For example, Hisense Optoelectronics Technology Co., Ltd. showed off its new 2.488/1.244-Gbit/sec GPON OLT transceiver. The two-wavelength (1310 and 1490 nm) device supports 32 splits over 20 km using DFB laser and APD receiver technology. The transceiver comes in 2x10 and 2x5 versions in an SFF package. Released in May, the device is in trial use by two "big customers" in the United States as well as "several" smaller customers, according to Xu Jun, marketing director at Hisense. While the devices come in standard form factors, Xu says that they have been customized for to match customer requirements. The GPON transceiver, released this past May, joins the company's line of GE-PON OLT and ONU transceivers.
Fiberxon also showed off FTTH transceivers, including a new triplexer-based ONU device. An EPON transceiver for OLTs that need to support 20-km distances also was on display.
LightComm trumpeted its coupler technology for FTTH applications, including a three-wavelength coupler. The company also provides coupler/filter combinations for OLT WDM requirements.
Accelink Technologies Co. Ltd. continues to offer a variety of components for optical access applications. These devices include a manual power splitter, 1x32 PLC-based splitters, tapped photodetectors, and GE-PON transceivers and triplexers. According to Xueyong Zhang, marketing support manager, the triplexer and variable optical power splitter are in trials, as is a WDM PON transceiver.
Finally, Wuhan Telecommunication Devices Co. Ltd. displayed several devices for GE-PON applications, including SFF transceivers for both OLTs and ONUs, as well as bidirectional devices, triplexers, and video receiver modules. The bidi has been shipped to Korea and Japan for point-to-point applications, a source at the booth revealed.
