DTR-1250-SM-LC/LS-CWDM  
3.3V LC connector SFF Gigabit Ethernet CWDM Laser Transceivers  
Features  
; Eight wavelengths (8) CWDM transceivers  
; Compliant with IEEE 802.3z Gigabit Ethernet  
1000BASE-LX PMD specifications  
; Eye Safe (Class I Laser Safety)  
; Excellent EMI & ESD protection (optional extra  
EMI shield also available)  
; Multi-sourced 10-pin (2x5) SFF (Small Form  
Factor) package style  
; Duplex LC optical connector interface  
; Single +3.3 V supply & LV-PECL DATA  
interface (AC coupling option also available)  
; LV-TTL TX DISABLE input & RX SIGNAL  
DETECT output  
Description  
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.  
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).
