Manufacturer: ZTE Part number: GFBT GFGH GFTH GFXH GFBH GFBL GFBT GFCH EFTH Port: 16-port Interface: XG-PON & GPON Combo Function: XG-PON & GPON service access Specification: XG-PON & GPON Combo SFP+ interface, with built-in internal multiplexing, SC/UPC optical connector Device Specifications Weight: 1.72 kg Dimensions (L x H x W): 393.1 mm × 23.9 mm × 214 mm ZTE 16-port GPON & XG-PON Combo service card GFBT Apply to ZTE ZXA10 C600/C650/C680 GPON OLT Supports 16 XG-PON & GPON SFP+ hybrid interfaces Maximum optical split ratio of GPON: 1:128 Maximum optical split ratio of XG-PON: 1:128 Support optical power monitoring Support the ALS function of optical modules. Support hot swapping GFBT is a 16-port 10G GPON (XG-PON&GPON Combo) OLT subscriber card, which can be applied to ZTE ZXA10 C600/C650/C680 GPON OLT. The combo PON solution multiplexes GPON and XG-PON optical wavelength channels in an optical module onto a single output optical port. For XG-PON upgrade, the carrier only needs to replace the GPON line cards in OLTs with combo PON line cards and cut the optical fibers on the , original GPON line cards over to the combo PON line cards, so that the GPON and XG-PON can operate together. Does GFBT support 16 XG-PON & GPON Combo SFP+ hybrid interfaces? Yes, GFBT Supports 16 XG-PON & GPON SFP+ hybrid interfaces: maximum optical split ratio of GPON: 1:128; maximum optical split ratio of XG-PON: 1:128. What is the difference between ZTE GFBT and GTGH interface card?
