XCVR-Q80V31 Ciena Compatible 100GBASE-ZR4 QSFP28 Transceiver

EdgeOptic's XCVR-Q80V31 compatible is a Ciena-coded 100GBASE-ZR4 QSFP28 rated for 80 km on G.652 single-mode fiber. The EdgeOptic compatible matches the original optical specs and ships with Ciena-recognised EEPROM coding, so Ciena Waveserver, 6500, and 5170 platforms accept the optic without unsupported-module warnings.

Four LAN-WDM channels at 1295.56, 1300.05, 1304.58, and 1309.14 nm, 25.78 Gbps each lane, 103.125 Gbps aggregate over two single-mode fibers (TX and RX) on an LC duplex connector. Cooled EML transmitters, SOA + PIN photodetector array, 30 dB optical link budget on G.652 fiber. NRZ direct-detection, DOM via the standard QSFP28 I2C interface. 100GBASE-ZR4 is MSA-extended from IEEE 802.3ba LR4 to reach 80 km.

Host RS-FEC is mandatory. ZR4 closes the 80 km link with RS(528,514) per IEEE 802.3 Clause 91 running on the host MAC; the module carries no internal FEC. Both ends must have RS-FEC enabled, otherwise the link will not stabilise. On Ciena platforms RS-FEC is configurable per port; verify the FEC setting on each 100G ZR4 interface during commissioning.

XCVR-Q80V31 is Ciena's module designation for the 80 km ZR4 variant in the QSFP28 line. The shorter-reach sibling in the same family is XCVR-Q30V31, a 30 km QSFP28 module with a smaller optical budget that targets metro spans below 30 km. Both modules use the same LC duplex connector and G.652 fiber type; pick XCVR-Q80V31 when the link exceeds 30 km.

Works on Ciena platforms with QSFP28 ports, including Waveserver 5 and Waveserver Ai for packet-optical data centre interconnect, the 6500 Packet-Optical Platform for metro and regional aggregation, and the 5170 and 5171 service aggregation switches. QSFP28 client port availability depends on the specific line card installed on each chassis. Verify the installed optic through the platform-specific CLI: SAOS on 5170 and 5171, Waveserver CLI on Waveserver 5 and Waveserver Ai, Site Manager on the 6500. The EdgeOptic module's EEPROM carries Ciena vendor and part-number fields, so platform output lists it as a Ciena-branded optic.

100G ZR4 80 km optics serve ISP backbone aggregation, metro core links, mobile core transport, and data centre interconnect spans where 40 km LR4 is too short and coherent ZR is more module than the budget needs. The four LAN-WDM channels sit in the ITU-T O-band, outside the C-band window where EDFA amplifiers provide gain, so these modules are intended for unamplified dark fibre runs.

Operating temperature 0 to +70 °C commercial grade. DOM per SFF-8636 reports per-lane TX/RX power, temperature, Vcc, and bias current on each of the four LAN-WDM lanes. On short spans under about 15 km the receiver can saturate on the upper end of the ZR4 TX range; insert a 12 dB LC inline attenuator on the receive side. Sibling Cisco QSFP-100G-ZR4-S, Arista QSFP-100G-ZR4, Hisense LTA1319-PC1, and Edgecore ET7402-ZR4 compatibles cover the same 80 km LAN-WDM ZR4 standard with vendor-coded EEPROM for those host platforms.
