Description
The DTR-1250-SM-GB-I product family of GBICs provides
long haul, single mode solutions for 1000BASE-LX Gigabit
Ethernet ports in a networking switch. OCP offers four
distance options to support 42km, 68km, 72km and 80km
links in the networking infrastructure. Option “H3” uses a
1310nm DFB laser and provides a minimum optical link
budget of 19dB, corresponding to a minimum distance of
42km, assuming fiber loss of 0.35dB/km. Options “H5”,
“H7” and “H8” use 1550nm DFB lasers, and provide
minimum optical link budgets of 21dB, 22dB and 24dB
respectively. Each corresponds to minimum distances of
68km, 72km and 80km respectively, assuming fiber loss
of 0.25dB/km. All transceivers are Class I Laser products
per U.S. FDA/CDRH standards. The “H3”, “H5” and “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-I transceivers are fully compliant
with Annex F of GBIC specification, Rev. 5.5 (except for
higher TX optical power and 1550nm center wavelength
option).
The 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.
