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.
