PECL or TTL Receiver Signal Detect Indicator Wave Solderable and Aqueous Washable
Lar Class 1 Product which comply with the requirements of IEC 60825-1 and IEC 60825-2
RoHS Compliant per Directive 2002/95/EC.
Description The OPT-1250xxxx ries from DELTA is a 1X9 transceiver module designed expressly for high-speed communication applications that require rates of up to 1.25Gbit/c. It is compliant
with the Gigabit Ethernet standards as well as 1x Fiber channel standards.
The OPT-1250xxxx transceivers are provided with the SC receptacle that is compatible with the industry standard SC connector. The post-amplifier of the OPT-1250xxxx also
includes a Signal Detect circuit that provides a PECL or TTL logic-Low output when an unusable
optical signal level is detected. (e order information)
The OPT-1250xxxx transceiver is a Class 1 eye safety product. The optical power levels, under
normal operation, are at eye safe level.
