Description

The DTR-1250-SM-GB-CWDM-I product family of

GBICs provides long haul, single mode solutions for

1000BASE-LX Gigabit Ethernet ports in a networking

switch. The transceivers are offered with two optical link

power budget options to support 62km (H7) and 70km

(H8) in the networking infrastructure and are available

in eight (8) wavelengths: 1470nm, 1490nm, 1510nm,

1530nm, 1550nm, 1570nm, 1590nm and 1610nm. Both

options use 1550nm DFB lasers to provide minimum optical

link power budgets of 22dB and 24dB. They correspond

to transmission distances of 62km and 70km, respectively,

assuming a total connector/splice/CWDM mux and demux

loss of 4.5dB, allocated system penalty of 2dB and fiber

loss of 0.25dB/km. All transceivers are Class I Laser

products per U.S. FDA/CDRH standards. The “H7”

transceivers are Class I Laser products while the “H8”

transceivers are Class 1M Laser products per international

IEC-825 standards.

The DTR-1250-SM-GB-CWDM-I transceivers connect

to standard 20-pad GBIC connectors for hot plug capability.

This allows the system designer to make configuration

changes or maintenance by simply plugging in different

types of GBICs without removing the power supply from

the host system.

The transceivers operate from a single +5V power supply

over an operating case temperature range of -5°C to +70°C.
