SFP-10G-ZR-S Description

The SFP-10G-ZR-S is a Cisco 10GBASE-ZR S-Class SFP+ transceiver for long single-mode links between buildings or sites. The module transmits at 1550 nm over ITU-T G.652 fiber for about 80 km on dual LC/PC connectors, draws up to 1.5W and operates from 0 to 70 degrees C. The module does not support Fibre Channel over Ethernet, so it carries Ethernet traffic only.

Application Scenarios

Long Single-Mode Site Links

Between two sites joined by a single-mode fiber pair of about 80 km, the module carries a 10 Gigabit Ethernet link from a switch SFP+ port at 1550 nm over dual LC/PC connectors.

Ethernet-Only Data Center Interconnect

For a data center interconnect that carries only Ethernet, the module serves as the long-reach uplink, and storage-converged traffic stays on other optics because the module has no FCoE support.

SFP-10G-ZR-S is the S-Class 10GBASE-ZR optic with no FCoE support, while SFP-10G-ZR carries the multirate ZR, ZW and OTU2/OTU2e ordering description at the same 1550 nm, about 80 km reach and 1.5W, so links that must carry OTU2/OTU2e or ZW traffic move to SFP-10G-ZR. Sites that need an industrial temperature class instead of 0 to 70 degrees C should order SFP-10G-ZR-I, which is listed at 70 km, draws up to 2W and needs an inline attenuator below 40 km. Spans that stop at 40 km fit SFP-10G-ER-S, the S-Class ER optic with a red latch and a 5 dB attenuator below 20 km, whereas SFP-10G-ZR-S uses 15 dB below 5 km, 10 dB from 5 km to 25 km and 5 dB from 25 km to 45 km.

Ordering Checklist

  • Fixed attenuators: Add 15 dB for links under 5 km, 10 dB for 5 km to 25 km, or 5 dB for 25 km to 45 km; the 5 dB spare is 15216 ATT LC 5=. Single-mode links shorter than about 40 km can overload the receiver without a matching inline attenuator.

    Our procurement lead was skeptical at first. After seeing the product, she approved the reorder.

    Long range link up and running. Thanks for the advice on the attenuation levels before purchase.

Questions & Answers

  • What receiver overload, sensitivity and damage levels does SFP-10G-ZR-S have?

    SFP-10G-ZR-S has a receiver overload of -7 dBm, a 10GE sensitivity of -24 dBm and a damage threshold of +5 dBm. Its transmitter output is 0 to +4.0 dBm, so a short unattenuated span can exceed the overload level and needs a fixed pad.
  • What receiver wavelength range does SFP-10G-ZR-S accept?

    The receiver accepts 1260 to 1565 nm. Sensitivity is specified over 1530 to 1565 nm, with 3 dB of degradation below 1530 nm, so light outside the 1530 to 1565 nm band reduces the usable sensitivity.
  • What chromatic dispersion limit and engineered-link rule apply to SFP-10G-ZR-S?

    SFP-10G-ZR-S tolerates up to 1600 ps/nm of chromatic dispersion. Links longer than 30 km are treated as engineered links, so the fiber loss and dispersion of each span should be calculated before the link is built.
  • Which attenuator spare PIDs cover short single-mode spans on SFP-10G-ZR-S?

    The attenuator spare PIDs are 15216 ATT LC 15=, 15216 ATT LC 10= and 15216 ATT LC 5=. They supply the 15 dB, 10 dB and 5 dB inline pads that the padding table assigns by span length, placed ahead of the receiver.
