Extended Reach (ZX) Small Form Factor Pluggable (SFP)
(NTTP51DZ)
OPTera Metro 3500 Release 12.1 introduces a new extended reach (ZX) small
form factor pluggable for the 2xGigE/FC-P2P interfaces.
The new extended reach (ZX) small form factor pluggable uses a 1550nm laser
and provides a minimum optical link budget of 24dB, which corresponds to a
minimum distance of 80km (assuming fiber loss of 0.25dB/km). The ZX SFP
provides a quick and reliable interface for 1000BASE-ZX Gigabit Ethernet
and 1.062GB Fibre Channel applications and is compliant with IEEE 802.3z
Gigabit Ethernet 1000BASE-LX PMD specifications and with 1.062GBd
Fibre Channel 100-SM-LC-L FC-PI standards.
Note: Loss-less flow control is guaranteed for LX distances.
Refer to
Table 4-15 on page 4-29
for specifications for the SX, LX and ZX
SFP.
