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.
Absolute Maximum Ratings
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
