Preliminary Data Sheet March 2001 1738U-Type Small Form-Factor Erbium-Doped Fiber Amplifier with Uncooled Pump Applications ■ Single-channel links in: — Metro systems — Long-haul transport — Switch matrix Description Compact size and extremely low power consumption make the 1738U-Type EDFA an ideal solution for single-channel, preamplification applications in C-band. Features ■ Economical, compact package: 90 mm x 70 mm x 12 mm ■ Extremely low power consumption: <875 mW ■ Single-channel amplification in C-band (1528 nm—1562 nm) ■ Uncooled 980 nm pump laser module ■ Wide operating temperature range: –5 °C to +70 °C ■ Optical input tap ■ Isolated input and output ■ Connectorized single-mode fiber pigtail The 1738U-Type Uncooled Small Form-Factor Erbium-Doped Fiber Amplifier (SFF EDFA) is designed for single-channel amplification in C-band applications. The device is manufactured in an economical SFF package and exhibits extremely low power dissipation over a wide operating temperature range. Optimum performance and system stability are supported through the use of optical isolation at the input and output. Optical input and output functions are achieved through single-mode fiber pigtails terminated with optical connectors. The EDFA incorporates an optical input tap and monitor photodiode. 1738U-Type Small Form-Factor Erbium-Doped Fiber Amplifier with Uncooled Pump Preliminary Data Sheet March 2001 Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.
