Hitachi and Northern Telecom develo¥fiberoptic transceivers
Hitachi (Tokyo, Japan) and Northern Telecom (Nortel; Paignton, England) have agreed to jointly develo¥laser-diode transmitter modules and photodiode receiver modules for next-generation optical-cable communication systems. The two companies will develo¥MiniDIL products--to replace current 14-pin DIL technology. The flat ceramic MiniDIL laser photodiode module is pin-compatible with the 14-pin DIL but measures only 13.2 ¥ 76 mm. The ceramic MiniDIL technology is based on a passive alignment system utilizing Nortel`s silicon V-groove technology and low-cost, ceramic MiniDIL modules that use Hitachi`s volume-fabrication technology. The companies also plan to jointly develo¥lower-cost plastic MiniDIL products; joint developments will also focus on extending the product lineu¥by the addition of 622-Mbit/s and 2.5-Gbit/s modules, according to a company statement.
