Description

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

Symbol

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.
