DETECT output
The DTR-1250-MM-LC-MR and DTR-1250-MM-LS-MR
fiber optic multi-rate transceiver offer a simple and
convenient way to interface 1000BASE-SX Gigabit
Ethernet boards running at 1.25 Gbaud to multimode fiber
optic cables. The multirate transceiver operates from Fast
Ethernet data rate (125 Mbps) to Gigabit Ethernet data
rate (1250 Mbps). A high reliability 850 nm wavelength
Vertical Cavity Surface Emitting Laser (VCSEL) is used in
the transmitter. All modules satisfy Class I Laser Safety
requirements in accordance with the US FDA/CDRH and
international IEC-825 standards.
The transmit and receive functions are contained in a narrow
width two-row, 10-pin (2x5) package with a Duplex LC
connector interface. The receptacle fits into an RJ-45 form
factor outline. The 10-pin configuration is in conformance
to a Small Form Factor (SFF) multisource agreement.
The transmitter and receiver DATA interface are differential
direct-coupled LV-PECL. An alternate version with AC
coupling interface is also available. An LV-TTL Transmitter
Disable control input is provided. The receiver Signal Detect
output interface is also LV-TTL.
The transceiver operates from a single +3.3V power supply
over an operating temperature range of 0°C to +70°C. The
package is made of metal for excellent EMI shielding.
