dtr-1250-sm2-lc OPLINK Communications Inc., dtr-1250-sm2-lc Datasheet - Page 4

• Manufacturer Part Number: dtr-1250-sm2-lc
• Description: 3.3v 2x10 Lc Connector Sff Gigabit Ethernet 1300 & 1550 Nm Laser Transceivers
• Manufacturer: OPLINK Communications Inc.

Interface circuit: Three options for
interface circuit are shown here: two
with DC coupling and one with AC
coupling.
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 posts (mounting
studs) should be grounded to Chassis
Ground. If Chassis Ground is not
available, they should be connected to
Circuit Ground.

1. For AC-coupled modules, please add suffix “AC” to the above Model Names.
2. For Plastic Package modules, please remove suffix “M” to the above Model Names.
3. For Industrial temperature, please add suffix “A” to the above Model Names.
4. The H3 & H7 options with “A” temperature range is only available from -25°C to +85°C.
Model (DC-coupled,
are DTR-1250-SM2-LC-A-L2-M and DTR-1250-SM2-LC-A-L2-AC-M
are DTR-1250-SM-LC-L2 and DTR-1250-SM-LC-L2-AC.
For example, Industrial temperature version of DTR-1250-SM2-LC-L2 and DTR-1250-SM2-LC-L2-AC
For example, the AC-coupled version of DTR-1250-SM-LC-L2 is DTR-1250-SM-LC-L2-AC.
For example, the Plastic Package version of DTR-1250-SM-LC-L2-M is DTR-1250-SM-LC-L2-AC-M
