Description
The DTR-1250-SM-LC-CWDM and DTR-1250-SM-LS-
CWDM fiber optic transceivers offer a simple and
convenient way to interface 1000BASE-LX Gigabit
Ethernet boards running at 1.25 Gbaud 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, and 1610 nm. Two performance
options are available. In option “H5”, a guaranteed
minimum optical link budget of 17 dB is offered which
can correspond to a link distance of over 35 km or 40 km
(assuming worst case fiber loss of 0.3 and 0.25 dB/km
respectively). In option “H7”, a guaranteed minimum
optical link budget of 20 dB is offered which can correspond
to a link distance of over 70 km (assuming fiber loss of
0.2 to 0.25 dB/km).

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.
All modules satisfy Class I Laser Safety requirements in
accordance with the US FDA/CDRH and international
IEC-825 standards.
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
module is housed in a metal package for excellent EMI
shielding.
