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.
