Description

The DTR-xxx-SM2-LC/LS-CWDM fiber optic transceivers

offer a simple, convenient way to interface PCBs to single

mode fiber optic cables in Coarse Wavelength Division

Multiplexing (CWDM) applications. There are eight center

wavelengths available 1470 nm, 1490 nm, 1510 nm,

1530 nm, 1550 nm, 1570 nm, 1590 nm, 1610 nm. For

OC-3 applications two performance options are available,

“L0” and “HP”. In option “L0”, a DFB laser and a high

sensitivity receiver are used to increase the distance to 90

km (assuming worst case fiber loss of 0.3 dB/km), and in

option “HP”, a high power DFB lase is used to improve

link budget and increase the distance to 100 km or better.

For OC-12 applications, the “HP” power level is used with

the DFB laser to obtain distance of at least 80 km.

All modules satisfy Class I Laser Safety requirements in

accordance with the US FDA/CDRH and international

IEC-825 standards.

Symbol

The transmit and receive functions are contained in a narrow

width two-row, 20-pin (2x10) package with a Duplex LC

connector interface. The receptacle fits into an RJ-45 form

factor outline. The 20-pin configuration is in conformance

to a Small Form Factor (SFF) multisource transceiver

agreement.

The transmitter incorporates a highly reliable InGaAsP Laser

and a driver circuit which converts LV-PECL data to light.

A LV-TTL Transmitter Disable control input is also

provided. The receiver features a transimpedance amplifier

IC with internal AGC for high sensitivity and wide dynamic

range. The Signal Detect status output can be either

LV-TTL or LV-PECL.

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

... If the SIGNAL DETECT output is LV-PECL level, a termination resistor of 160 ohms to GND is required. Interface circuit: The power supply line should be well-filtered. All 0.1 µF power supply bypass capacitors should be as close to the DTR transceiver module as possible. The two front GND - 1.3 V, the CC posts (mounting studs) should be grounded to Circuit Ground or Chassis Ground ...
