JUNIPER EX-SFP-GE80KCW1470 TRANSCEIVER

EX-SFP-GE80KCW1470 1470nm CWDM Optic

EX-SFP-GE80KCW1470 is Juniper's 1GbE SFP for the 1470nm CWDM channel and an 80km single-mode-fiber reach class. Juniper assigns part number 740-032291, a duplex LC PC/UPC connector and digital optical monitoring.

CWDM channel planning comes first

The 1470nm wavelength must match the mux/demux port and the corresponding remote-end design. Inventory the entire optical path, including passive CWDM filters, add/drop elements and any intermediate patching. A cage-compatible SFP with another wavelength cannot substitute without changing the channel plan.

This is not a single-fiber BX pair

The optic uses separate transmit and receive fibers through duplex LC. It does not pair with EX-SFP-GE40KT13R15 or EX-SFP-GE40KT15R13, which are complementary 40km single-strand BX modules. Confirm fiber polarity and duplex continuity rather than applying a BiDi wavelength-direction rule.

Engineer the 80km budget

The stated distance is a product reach class. Validate launch and receive limits from the exact HCT specification, then subtract fiber attenuation at 1470nm, connector/splice loss, mux/demux insertion loss and engineering margin. Chromatic effects, plant age and restoration splices can make a nominally shorter route fail the budget.

Host and operations gate

Use Juniper HCT to verify the switch/router, interface module and Junos release. At commissioning, record PID, part number, serial, channel, mux port, TX/RX fibers and DOM values; check alarms and errors after the link reaches thermal stability.

Receiving checks

Inspect the Juniper label for exact GE80KCW1470, not a neighboring CWDM wavelength. Verify duplex LC cleanliness, the intended 1470nm mux port and matching endpoint BOM before installation. Preserve optical readings as the baseline for future attenuation drift.
